I'm starting to catalog everything and set a price point, but I'm still not entirely sure about the various amounts. I've decided to try and sell the original sketch to the recent Batman Beyond piece on eBay and see what that goes for. Whatever it goes for won't be the set-in-stone price for all the pieces like it, but I'm hoping it will give me a better idea of what the going rate might be. I've never sold anything on eBay either, so I'm seeing if it works out alright. Still might do it from time to time in the future.
Anyway, here's the link to the auction: [link]
Bidding ends on December 17th.
