Gernale assisted Redondo on the art as revealed on the letters page. Patchwork Man first appeared in Swamp Thing #'s 2 and 3.
Patchwork Man was intended to be an ongoing feature but House of Secrets was cancelled with this issue. When it was re-instituted five months later the series was dropped and the title reverted to its regular mystery/horror format.
