Well, since Allen & Ginter blaster boxes have not hit the local Target's and Walmart's yet, I am still confined to eBay and various message boards for my A&G fix. I noticed this insert set on eBay:
2010 Allen & Ginter Celestial Stars Set
I found the Allen & Ginter Celestial Stars checklist but not much else about it. I did see on the Blowout message boards that they may (or may not) be the key to the 2010 Ginter code and that they appear to be falling at one card per case. They are all big name players. Anyone seen any retail blasters yet?
