I've been a few times over the last few years, and it is like you said, a few things, selected around a theme. It rotates every 6-12 months, maybe? Last time I was there, it was the boxing cards, which were displayed with some of the museum's collection of boxing art and photos. It was really well done, and extremely interesting. Before that, the one I saw had a lot of baseball cards, grouped in frames of about 20-30, from various sets. It's funny that they will display the cards, and on the wall will be the description, with the players' names. If a card is damaged, where the name is not readable, the wall placard says "Unknown." It would take about two minutes of research to figure out who the card is, but they don't bother, which always seemed to be weird to me. Anyway, it's well worth seeing. And check out the room with the armor and muskets...awesome! And Washington Crossing the Delaware, which I could stare at for hours.
