Back in 1971, Mayer did some material as a proposal for a book collection of comics as THE POCKET-SIZE TREASURY OF SUGAR AND SPIKE STORIES.
It didn't come out, of course. Too early, I guess. Just had to wait another 40 years. Still, a nice cover. This copy of it is from COMIC BOOK ARTIST #11  from TwoMorrows, a flip-book issue with one side devoted to Sheldon Mayer (guest edited by Bill Alger) and the other to Alex Toth (an artist who Mayer hired back in the 1940s). You should try to find a copy if you're interested in Mayer's work. TwoMorrows is sold out of the print edition, but has a digital version available.
