Manga Books in the U.K., a division of Manga Entertainment, published Biohazards and Dangerous Acquaintances in this "manga book" format ( 5-3/4 x 8-1/4 inches [15 x 21 cm.] ) on high-quality paper; here are the book jacket and front cover for Biohazards, issued in September 1995 (ISBN 1-900097-04-4); the jacket art is by Wil Overton (I suspect he was not given Warren's comic for reference and was working from a verbal description of the character designs, so the result is a curious amalgam of comix and DP Flash details)
the book jacket and front cover for Dangerous Acquaintances, released in January 1996 (ISBN 1-900097-06-0); the jacket cover art is by Kevin Walker, based on one of Warren's comix covers for the series
Dark Horse released a 1/6-scale double statue of the Angels on 17 April 2002 and a set of 1/6-scale action figures on 9 October... [see the Warren-inspired section of "Go Figure!"]
