Since non-sport manufacturer Inkworks closed up shop a few months ago, much has been speculated about their remaining inventory. There was a noticeable upturn in the number of eBay listings, particularly from a couple of sellers. Then there was Razor's grab bag release Ink Archives that had one random Inkworks autograph per pack.
Factory Entertainment has now launched InkworksArchives.com, which should answer a lot of questions about the leftovers, particularly autographs, Pieceworks costume cards and sketch cards. There's also a lot of promo cards and uncut press sheets, which were an Inkworks staple.
I've only done a quick browse through what's available but it should give an indication as to what there was lots leftover on. For example, there's lots of Golden Compass cards, but very little for either of the Alien vs. Predator set. Of course, this could change if more items are listed on the site, but it's a good first look.
