Rebelscum.com notes "one of the hardest to find vintage variations" of a Kenner Star Wars action figure, the elusive Orange Hair Luke Skywalker, has appeared on eBay. The figure is "carded", i.e. in its original packaging, and graded by the Action Figure Authority, an outfit that grades collectible toys.
Orange Hair Luke can be yours now for US$6000. You can buy it, admire it within its protective plastic case, wonder at how orange its hair is (although it's more like yellow-brown, judging from the photos), then display it in your living room so all your friends can see how rich and stupid you are.
Or you could take your excess cash and do something good with it.
