This ad is from August 24, 1968. I am still not sure when exactly Dick Bennick's character switched from Count Shockula to Dr. Paul Bearer as host . I am going to keep doing research. One thing for sure, I was a big fan of Shock Theatre and all of the shows Dick Bennick hosted during his time at WGHP. Even after he left the Triad and moved to Florida, video segments of Dr. Paul Bearer were still used on Shock Theatre well into the seventies.
