In addition to a unique logo, each Olympic games adopts a mascot. The mascot usually appears in the Opening Ceremonies and on some memorabilia, especially children's items.
"Izzy" was the 1996 mascot, and my Atlanta commemorative set includes four pins featuring him/her/it. This unusually shaped pin shows Izzy, a cute little cartoon character, against a white background carrying the torch.
Shown again carrying the torch, this Izzy doesn't have a background..
This pin shows that Izzy is also patriotic, depicted here carrying an American flag.
Here Izzy is shown playfully peeking out from behind a green logo pin. While I don't really care for the mascots, I have to admit that this pin is one of my favorites.
