This is a beautiful lot. Shame you have to sell. I understand you want this gone in one quick sale. I just dunno how much luck you're going to have. Especially at the Arena. Have you tried at the Kenner forum?
If you do decide to split up the hoard, requesting that people buy no less than five items, might help you get rid of it quickly. I'd be interested in a few small pieces, I hope you consider splitting up the lot.
