What a terrific idea - a record (the old-fashioned sort played on a turntable) printed on a cereal box. These seem to have been quite common in the US, but although here in the UK it was possible to get novelty records printed on postcards, for example, I don't recall ever seeing these as cereal give-aways.
This one is surprisingly good. The Legend of Sleepy Hollow given away with a cereal in the 1970s. Just over 3 minutes of spooky thrills best enjoyed while eating a bowl of cereal just before bedtime on a dark stormy night!
As marvelous as the Luminous Spook promotion was, if only Quaker had somehow managed to fit a recording (perhaps the soundtrack from the TV ad) onto the cereal packet (along with the 3D Haunted Manor), it would have been perfect.
