Fellow fan Michael Caffrey has posted images of an insane find on the TRANSFORMERS ADDICTS! group on Facebook. The photos show what appear to be the original "Birthday Party" costumes of G1 Jazz and Thundercracker. These were likely rentals used for kid's birthday parties. You can see the costumes in the commercial below:
At this time it appears the costumes will ultimately be put up for sale. I suspect some uber collector is going to pay a pretty penny for these amazing pieces of Transformers history.
