There's no denying the popularity of the Barbie doll (what girl didn't have one when she was a kid?), and for her 50th birthday, Strong National Museum of Play is celebrating America's favorite doll with a huge year-long exhibit.

More than 500 of the petite, plastic girls are currently on display at the museum, and will remain there until next June. The exhibit features Barbie's friends, including her infamous off-again, on-again beau, Ken, dress-up areas and interactive learning stations that have info on everything Barbie. (Did you know her real name is Barbara Millicent Roberts? Or that she's had nearly 50 different careers during her existence?)

The exhibit is free with admission to the museum, which ranges from $8 to $10. Strong Museum (1 Manhattan Square) is open Monday-Thursday 10 a.m.-5 p.m., Friday-Saturday 10 a.m.-8 p.m., and Sunday noon-5 p.m. Visit museumofplay.org for more info.
