Ebay is probably the best place to post it up. It's just too bad they charge a high fee. I don't know if you or he will get much if you only ship within the 48 states but some of the guys in Germany will pay top dollars for it. Otherwise post up a picture of the condition of the package because that speaks volume by itself. Collectors value the complete package including the condition of the box.
