It's A Puzzle, Scooby-Doo

Ever since its debut on CBS in 1969, Scooby-Doo Where are You! and the many iterations that followed has provided plenty of Halloween-esque horrors, even though the Mystery, Inc gang usually uncovers (or unmasks) the terrifying threat to be a decidedly down-to-earth plotter. As with all Hanna-Barbera hits, Scooby-Doo has been heavily merchandized, resulting in such spooky season-worthy treasures as these two vintage puzzles.
