Earlier today I finished up a trade of '09 OPC baseball with Tom from Cardboardsingles. It's a fairly new blog as Tom is just getting going.
He saw my post about needing some more OPC, and as luck would have it, he had just finished posting a blaster break of the stuff. Tom sent me an email, and voila! A swap.
Head on over to Cardboardsingles when you get a chance. Tom seems to touch on football, baseball and even basketball (although we won't hold that against him)
