Every February 28th is supposedly National Tooth Fairy Day.
The Secret Adventures of the Tooth Fairy was a two-minute comedic radio serial created by Dick Orkin in the early 1970s. 325 episodes were produced and eventually ran on over 2,500 radio stations worldwide.
This set of Tooth Fairy stickers was put out by 890 AM WLS (World's Largest Store-from when the station was owned by Sears) in Chicago, Illinois. Unfortunately, half of the stickers are missing but you can see the complete sheet here.
