LJN released several sets (6 total, I believe) of D&D puffy stickers in 1983 that are still pretty easy to find. The Larami releases, however, are extremely rare. I’m missing at least one of the sets. These sold on eBay some time ago for hundreds of dollars.
All of the characters and monsters seen here appear in the Dungeons & Dragons animated series. I know because my four-and-a-half-year-old daughter has been watching the show obsessively for the last several weeks. My youngest (19 months) much prefers Thundarr the Barbarian. Elmo is a close second.
