The Swamp Thing #1 in context
Why collectors care
The first issue of Swamp Thing's own series, cover-dated October-November 1972, by Len Wein and Bernie Wrightson. The Wrightson art on this run is among the most admired horror work in mainstream comics.
How to identify it
Swamp Thing #1, 1972. This is NOT the character's first appearance -- that is House of Secrets #92 (July 1971), also in this catalog. This issue retells the origin with a different protagonist name.
Common mistakes
Paying a first-appearance premium for the first solo series. The House of Secrets #92 debut is the more valuable book.
Grade considerations
An early-70s book with a dark, detailed cover that shows wear readily. High-grade copies with white pages command the premium.
