2008 Topps Co-Signers Baseball Forum

The attached pictures are clearly just for identification purposes. Clearly, not trying to meet uploading standards. I took the front pic at an angle so the silver reflective background could be seen easier. I can't find the card listed under either player (Lance Berkman & Roy Oswalt). Nor can I find the card with these two specific players in any of the Topps Co-Signers sets listed on this site. There is a serial number on the back of the card at the top /300. Please advise, thanks!
