I am trying to find the name of the artist who did the cover art for
the 1987 (also 1991..http://members.tripod.com/~v_m_smith/91scf.htm)
version of "Stranger in a Strange Land" by Robert A. Heinlein...for
some reason I can't find this info (but I don't own
the book). MOST IMPORTANTLY I want to know how to get a print of it,
in any form possible. THANKS!!...

The cover artist for the 1987 and 1991 Ace editions of "Stranger in a
Strange Land" was James Warhola, the nephew of Andy Warhol.

"Stranger in a Strange Land (Ace 0-441-78838-6, Oct ?91 [Sep ?91],
$9.95, 525pp, tp, cover by James Warhola)"
