This is a collection of The Simpsons - World of Springfield figures. This series was produced between 1999 and 2004, with over 200 different figures released. There were also 40 playsets and 3 dioramas. The seller is also including six Franklin Mint Simpsons plates, along with some other stuff.
Hard to say if it’s the complete collection because the listing is a mess, just one huge paragraph. Anyway, there is a lot there, and the starting bid of $2,000 is good value.
