John Wayne Gacy executed by the State of Illinois on May 10, 1994.

8 1/2" x 14" photocopied page mailed in June of 1982 to his chief investigator depicting the Seven Dwarves witnessing an execution.
Gacy has included a handwritten note on the back I assume that "Thompson" is in the electric chair but I do not know who Gacy has depicted pulling the switch. Gacy has written a note on the back in which Gacy has signed his last name. It reads, Exclusive! Gacy's answer to Thompson.  ("Art critic.").
Includes the original prison mailed envelope postmarked June 22, 1982.
