Always digging around, John D. Haefele uncovered a fanzine report of a party held in Milwaukee in 1940 — a science fiction and pulp gathering anchored by solving an appropriate rebus puzzle.
Meeting in the home of Ralph Milne Farley of The Radio Man fame (also a state senator, but let’s keep it fun here), guests included Robert Bloch — with Psycho not quite 20 years in his future — and Ray Palmer, editor of Amazing Stories.
Spoiler: Bloch came in second place in the game.
