Zu Zu Ginger Snaps Used in 1918 Psychological Study to Determine Guilt or Innocence

In 1918 Harry W. Crane published a psychological monograph detailing a study conducted to test “the association reaction as a test for guilty knowledge of crime.” He wondered whether he could tell if someone was guilty or innocent by testing their reaction times in a word association test. He took a group of students and secretly selected some of them to commit a “crime.” Here are the first set of instructions given to the “criminals.”

1918 Study

First set of instructions for the “criminals.”

Once in the auditorium they were to interact with a group of objects on a table which included a candle, a couple of books and a box of Zu Zu Ginger Snaps, among many others. The idea was that they should spend some time with the objects (reading pages of a book, hiding an object of their choice, eating the snaps, etc.) so that those objects – and words associated with those objects – would imprint on their minds.

Then the whole group (guilty and innocent) was given a word association test. It was felt that the words on the list that corresponded to the objects in the auditorium would ferret out the “guilty” parties. According to Mr. Crane the study proved his theory. Should you choose you can read the whole monograph yourself here.

I think it speaks to the pervasiveness of ZZGS that they were included in a psychological study just after the turn of the century. Not only that but they were included, one might suppose, to appeal to a college student (one of the instructions was for them to eat anything they might like). Does that mean that ZZGS were somewhat common among that age group (18-21)? Or does it say more about the mindset of the person conducting the test (probably older, maybe much older, than the students)?

More ZZGS Carton Slips

After my previous posting about carton slips I was contacted by John Barney who has over 300 carton slips in his personal collection. He sent me a few ZZGS slips which I’ve posted here. The almost ethereal look these photos have are due to the plastic sleeves in which the slips are kept. Thanks to John Barney.

The Snappiest Ginger Snap You Ever Tasted (poster)

Ryan Obrist (“a collector of national biscuit advertising”) was kind enough to let me publish his wonderful ZZGS poster. It features the ZZGS Clown, is 15″ tall by 12″ wide and printed on paper. The tagline (“The snappiest ginger snap you ever tasted” makes me want to compile a full list of all their taglines. I did a quick look through some turn of the century newspaper ads sent to my by my friend Pau and the closest tagline to this one I could find was “The best ginger snap you ever tasted.” It will be interesting to see as I dig more if this same exact phrase pops up again. Thanks to Ryan.

ZZGS Carton Slips



Click to enlarge

My friend Pau in Barcelona kindly sent me a beautiful image of a page out of the September 1915 issue of The Printing Art (“An Illustrated Monthly Magazine Devoted to the Graphic Arts”). It is an ad showing what are called carton slips (one of which is ZZGS), all from the National Biscuit Company (NBC, later Nabisco) printed by the Edwards & Deutsch Lithographing Company of Chicago. The ad is promoting the relatively new offset printing process for marketers and advertisers. Offset printing provided a greater impact with more color and greater detail at less cost.

Carton slips were an early form of cross marketing. NBC would put these slips for one brand into the carton or package of another of their products. From an article in the same issue, “The plan of this biscuit company is to include in each box an advertisement of one of the other products, so that users of one food product may learn about others manufactured by the same company.” According to Charlie Brown, “National Biscuit Company put these beautiful “SLIPS” inside different packages of their biscuits. Example, the Graham Cracker insert was placed most of the time in NBC’s Sugar Wafer packages. ZuZu could have been placed inside their Sugar Wafers products.”

It was brilliant, cheap and very effective.

Charlie Brown, as always, was kind enough to send me some photos of different NBC carton slips from his collection. Click on the first image to start a slide show. Thank you Charlie.

Zu Zu Ginger Snaps Trademark Infringement

Zu Zu Ginger Snaps was the target of many trademark infringement attempts. As I wrote in an earlier post it is amazing the companies that lined up to cash in on the hard work and successful marketing of the National Biscuit Company (NBC, later Nabisco). It’s hard to imagine but products that ran far afield of ginger snaps, cookies or even food items took aim at ZZGS’s popularity. One such infringement was a cigar company (see the image below). I’m not sure how the good will of a cookie marketed to children would translate into cigar sales but try they did.

This image comes via the oft-thanked Charlie Brown and his and his wife Prissy’s blog The Inner-Seal Collector’s Club. Check it out and let Charlie and Prissy know if you appreciate their work in keeping the NBC flame burning – and that includes ZZGS.

Baby Zu Zu

At only 15″ tall this “Baby Zu Zu” is the largest of the two Zu Zu dolls produced. Recently obtained by Charlie and Prizzy Brown (of whom I have written much) he is a sprightly 98 years old. They were originally sold with the Zu Zu Clown hat but almost all were lost as they came off so easily (this one amazingly had his). Thanks for sharing Prissy and Charlie.

Doll House Grocery Store with Zu Zu Ginger Snaps

Gail Carey from Little Things Loved has kindly sent some photographs of what appears to be the only Nabisco product included in a non-Nabisco toy. It is a doll house grocery store sold by F.A.O. Schwarz between 1918 and 1919. On the shelf behind the grocer is a stack of Zu Zu Ginger Snaps boxes. The manufacturer is unknown but given the presence of the Zu Zu Ginger Snaps and Kellogg’s Crumbles and Uneeda Biscuits (another Nabisco product – actually National Biscuit Company, later Nabisco) this is probably an American toy. And it is a testament to Zu Zu Ginger Snaps’ reputation at that time that they were included.

Most of this information comes from “The Small World of Antique Dolls’ Houses” by Flora Gill Jacobs. Again, thanks to Gail Carey for sending me a scan of page 348 with said mention.

And thanks to my “go to” source for all things NBC/Nabisco, Charlie Brown. I asked him if he knew of any other NBC/Nabisco products that were included in non-Nabisco toys. He said there were a few Nabisco toys using their own products such as “the Uneeda Boy doll has a box of Uneeda Biscuits under his arm, the National Biscuit Horse Drawn Toy Wagon, had Uneeda Biscuit, Grahams, Premium, Barnums & Shredded Wheat Wooden boxes, paper  overlay. The “Feed Me Bear”, Circa 1920’s had a box of  Barnum’s  Animals with the bear. The national Biscuit Truck & Double Trailer had NBC products inside. Of course Master Zu Zu had the miniature Zu Zu String box with the doll.” But apparently no inclusion of Nabisco products (even in non-edible form) in any non-Nabisco toys. So this appears to be a very rare item indeed.
