"Dr. Thirteen Believes in Ghosts" from Ghosts #100 (DC, 1980) by Howard Bender and Tony DeZuniga
Terry Thirteen shilling for Ghosts? I guess someone has to, and he WAS a regular feature at the time. The series, which started out as "True Tales of the Weird and Supernatural" and later fessed up to actually being "New Tales..." was one of DC's supernatural mystery books through the 70s, and far from the most memorable. It still managed to get to 112 issues, so it must have had readers. Anyone want to admit to it?
