The Ova Hamlet Papers by Richard A. Lupoff.
First (and only?) edition was limited to 1,000 copies and featured stories originally printed in Fantastic Magazine from 1969 to 1976. Seems these only go for about $10...
Trina illustrated more for Lupoff later too. His 1988 book The Comic Book Killer included a faux Golden Age comic book (ed. of 500) in its limited edition slipcased version. The comics are drawn by Trina and Steve Leialoha.
