Did you know Bill advised The Batman on a case?
Copyright 1981 DC Comics.
In this panel from The Brave & the Bold No. 178, The Batman explains
information about origami to the Creeper -- which he got from William F. Wu,
Ph.D. So is Bill an art dealer? Not as such -- but he does have a modest
collection of original comic book art. This story, “Paperchase,” was written
by Alan Brennert, who also adapted “Wong’s Lost and Found Emporium” for The
Twilight Zone tv show, and illustrated by Jim Aparo.
