My latest pickup is this black autograph card from the Team USA set. I already had the blue and red versions, which were numbered lower than the /595 of the black. I'm not sure why I didn't get the easiest one first, but I've got it now.
Including autos and relics I've now got eight Barney USA cards...take a look.
To satisfy my need for symmetry, I'm guess I'll have to get the blue auto-relic card.
