Some guy on Blowout messaged me that he had a bunch of Seneca Wallaces, including a /20 I needed. When I asked what he wanted for it, he said he'd trade, but I have nothing he needs. So I offered money and he said no...just trade.
So anyways, if you know anyone with rare-ish cards of the guys in the title in Nebraska uniforms (autos, relics, whatever), I am definitely in the market for them now! Message me or comment if you think you might be able to help.
