NOTE:  this issue has come under debate.  Amy from the Netherlands emailed me to let me know that Tommie is actually a dog, not a bear, and that she confirmed this with the Sesame Street "Brand Coordinator" in the Netherlands.  I checked the Sesame Street site in the US, which says, "Tommie is a teddy bear/dog character".  Well, that certainly clears it up!  I agree with Amy that this is not a bear issue, but I'm going to leave this issue on the list so I don't get email from people who think it is a bear simply because their catalogs say so.  Collectors should use their own judgment on this issue.
