These are a pain. I'm working on a master checklist for the 2008 set as well. As far as I can tell, these were SGA's at different parks, or used for promotional materials by different teams. However, the checklist is continually numbered. At least, this seems to hold true for 2008 - I imagine 2007 is the same way.
Anyway, for 2008, I can't find a checklist posted anywhere. I took the partial team checklists from our site and then moved on to other avenues but wasn't able to add much by searching. There doesn't seem to be a comprehensive checklist posted in any location.
I'll never quit collecting entirely, but I am downsizing. Check out my COMC store and help me thin out what I don't want so I can buy cards that I do want. See something you like? Send me a message on here, and we can knock the price down quite a bit. I'll even take a bit of a loss if it means getting you a card you really want.
