2017 MARKET UPDATE:
There is no special reason for this book to be hotter this year, but it's a notoriously tough book that's under-valued in high grade. Its dark cover makes it almost impossible to find in grades of 9.0 or above.
Wrightson is only second to Neal Adams in popularity of 1970s artwork.
Bernie Wrightson is a hot comic book artist at the moment, and Swamp Thing is without doubt his finest hour.
Swamp Thing TV and Movie rumors are rife. Along with HoS92, there are two other Swamp Thing books on the Hot 100 list:
Swamp Thing #1 (classic cover by Wrightson, tough in high grade)
Saga of the Swamp Thing #37 (1st John Constantine)
House of Secrets #92 is among the most expensive 1970s comic books, especially in high grade. The dark purple cover featuring the classic "woman realizing she's not alone" image is awfully prone to wear and creasing.
Stick to VF+ or better. If you can't afford such a nice copy, wait until you can. Lower-grade examples are common, and make poor investments in our opinion.
