Research continues for the book. Recently I acquired something I did not know existed, although I should have know since it is a common enough practice.
Most of you are probably aware of the HUGE tie-in campaign in 1951 by Libby, McNeill & Libby, commonly known as Libby's. They had a double page spread in Life magazine that I'm sure many of you have seen, and a big in-store display kit. But they also produced newspaper ads that I have seen in lots of local papers, there was probably an advertising kit too because I have found lots of local newspapers with unique ads, some even with full and double pages, featuring the characters.
But this was new. It is a double-page broadsheet, likely circular or newspaper ad, but only printed on one side, and used by the grocery store as an in-store ad, usually taped to the inside of a window for shoppers to see as they entered the store.
Could Libby's not decide which spelling to use, so they blended them into "CATCHUP"? Sound like a very tardy condiment indeed.
