The icon image came up with "1956 halloween" as the search.
It may or may not be from a real 1956 cookbook but it looks like it.
The picture I chose was reliably a 1956 image, from the movie Forbidden Planet which premiered in March of that year. I expect it was shown as a Halloween film in some places, since it had the scary monster from the Id (shown) and a super-intelligent robot AND a romance between then-hunk-star Leslie Nielsen and hottie Anne Francis.
