Thanks. I thought so too when I saw em which is why I didnt wanna just frame them with whatever but at the same time I didn't wanna spend too much that the frame is more expensive than the item itself.
I got them from ebay... uhmmmm not sure if it was 2 or 3 years ago.... as per the ebay literature in the auction - it was part of an exhibit of Transformers art in the US. There are still several from that same exhibit that that particular seller is selling. I just can't remember the seller's ID.
