I made the mistake of buying the showcard for Rent before the show, and I wound up hating it (sorry, but I'm an Opera fan, and prefer the opera). If I like the show, I will buy a t-shirt (I did that for Lestat, because I thought it might be a necessity, even though the show was godawful). I often buy a refrigerator magnet, but stopped buying showcards.
Pardon my bluntness, too, but they had leather bands for Lestat that looked, well, like****rings. When I asked the man selling the stuff, he laughed, and told me that I was the first one who asked that, but that I was right. That's what they looked like.
If you want refrigerator magnets, Theatre Circle has lots of them on sale. Enjoy NYC.
