H.R. Pufnstuf Cereal Promo

Here's a Froot Loops cereal box back and side panel from 1970. It features Krofft's H.R. Pufnstuf and the free fun rings that came inside. The side panel has the mail-away offer for a Freddy the Flute instrument.

Too bad it's not a complete box, but I'm not really complaining...
