A surprise for my mom...Help please?

Okay, my mom's birthday was last week. I had this thing planned, but now I'm not sure it'll work (I told her we could do it this week). The day we're supposed to do it is TONIGHT... I need any museums within an hour or two of upstate New York that have any older stars (Grace Kelly, Audrey Hepburn, Jimmy Stewart) or people like Alfred Hitch. I'm looking for museums on them, or that have exhibits with them... Maybe an old movie stars kind of thing? If I could get the name of the museum and a website, that'd be great. Even if it's much farther away, go ahead and give me the name/link, because we still might be able to go... I'm only 13, so I'm just giving her mapquest directions and letting her find out where we're going when we get there ^_^ Thanks so much!
