Wow, I didn't even know those soap vinyls existed for pre-Cybertronian forms of Starscream and Bumblebe. I just picked a set up on eBay for 50 shipped, but there were others at much higher prices. Thanks for the photos - they look so cool.
I remember there was a Japanese summer festival one of these two chars that I could never acquire. This will do nicely, but I am sure would sell like hot cakes at a much lower price
On the lookout for MISB Headmaster Highbrow, Takara or Hasbro. I'm sure I could make you a sweet deal!
