Sesame Street stacking puzzles

Tyco produced a line of Sesame Street stacking puzzles in 1996, which assembled to form the faces of Big Bird, Elmo and Ernie. The toy set was updated in 1998, after Tyco was purchased by Mattel and the Sesame line was rebranded as Fisher-Price. The new set replaced the Big Bird puzzle with Cookie Monster and Oscar the Grouch.
