Now, for our special Halloween story)—The Flintstones Meet Frankenstein and Dracula. Naturally, the inclusion of the Wolf Man and the Mummy would have made the feature a much long title.

From The Flintstones #33 (April 1966)—script by Vic Lockman and drawn by Phil De Lara, a former animator for Warner Bros. that went exclusively into comic book work for Dell and Gold Key.
