These are Sesame Street protos from Toy Fair 2004 or 2005. They show Series 1 in it’s entirety without accessories. The original plan was to have each figure come with a piece of Sesame Street until the whole neighborhood was built. The idea was scrapped before they (almost) went into production. It was said the playset pieces were going to be distributed through mail order or other means. Arghhhh! *tear*
