Shock on Ebay
Shock magazine Stanley Publications, Inc. 15 issues. May 1969 - September 1971.

The first issue of Shock, with its May 1969 cover date, was the first comics magazine from Stanley Publications; Chilling Tales Of Horror followed the next month.

Stanley's books were very much like clones of the existing Eerie Publications titles; they primarily stuck to reprinted material (with a few touch-ups) in the beginning, featured new, lurid covers, and were generally produced as quickly and as cheaply as possible.

Shock, like the rest of the Stanley magazines, suffered from a relatively short supply but also small demand (relative to Eerie Pub. and related titles), so collectors can usually get them fairly cheaply.
