Wow! It's the house! I had so much fun with that thing when I was a kid. It looks like it's in great shape. I remember it having Bert and Ernie, Big bird and a nest, Oscar (in can, of course), Mr. Hooper, Gordon, and I think Maria. There were beds, a garbage truck, and a set little seats and counter for Hooper's store. There may have been some chairs, but I might have swiped them from another Fisher Price set.
Oh, and a lightpost with a sign that said "Sesame Street" and a triangular piece of sidewalk with a firehydrant in it.
(making that list was fun!
