I've been trying to find whether they reopened the USPC museum when they moved the factory to Northern KY. There is a notice that the one down south closed in 2001, but nothing since. Really fortunate that Howdy and Kregg got the antique chip photos from the museum when they did.
I got the two USPC Museum posters that were in the Club auction this year. They are relatively modern (1987, 1995) but well done and show many of the old card designs (and a few old chips).
