Here’s another encrypted text from an advertisement. It comes from Canada.
Over the last two weeks, I blogged about a new advertisement poster blog reader George Lasry spotted in a London subway train and about an advertisement series published in the 1930s (discovered by blog reader Rossignol). Today, I am going to introduce another advertisement bearing an encrypted message. This one was launched in the mid-1980s in Canada. To my regret, I only have a description of the ad, but no photograph or scan of it. Perhaps, a (Canadian) reader can help.
The advertisement in question was introduced in an article titled Cadbury Code Confidential in Cryptologia 4/1986. The article mentions a crypto enthusiast named Richard Outerbridge from Toronto. It is probably the same person who today runs the Twitter account @outerbridger (I don’t know if it is still active; the last tweet was published in 2013). Many of Outerbridge’s tweets are about cryptologic topics.
Here’s an excerpt from the Cryptologia article:
Some time ago Richard Outerbridge of Toronto, Ontario noticed an interesting CARAMILK …
… subway advertisement. The message read:
“After years of public pressure, Cadbury finally explains how we get the soft, creamy caramel inside the Caramilk Bar. [In code, of course. After all, we don’t want everybody to know.] Over an opened Caramilk Bar appears a replica of a memorandum. It reads as follows:
Cadbury Schweppes Powell Inc.
Cadbury Division CONFIDENTIAL
There follow routing slip names with signatures for President, Vice-President Marketing, Marketing Manager, Product Manager, and Technical Manager.
Can you break this cryptogram?
The solution is available on a Canadian website that can be found via Google. I’m sure, it will also be available on this page soon.
