A two-layer molded salad with a ham layer and a cream layer. No, seriously, it is. I found a picture and everything.
A variation of this recipe appeared in the May 16, 1960 edition of the Lawrence Journal-World.
A picture of that variant of the recipe (which calls for cherry-flavored gelatin, among other tweaks) appeared in the Dec. 2, 1965 edition of The Milwaukee Journal.
