PHILADELPHIA (CBS) — Philadelphia’s enticingly creepy Mütter Museum celebrates its 150th anniversary this weekend.

Do you want to see skulls, mummies, even pieces of Albert Einstein’s brain?  That’s what you’ll find at the Mütter Museum of the College of Physicians of Philadelphia, near 22nd and Market Streets in center city.

Last year more than 130,000 people stopped by.  Museum spokesman J Nathan Bazzel (right) says to celebrate its big anniversary this year, everyone is invited to stop by this weekend, and then to take part in special activities on Monday.

“Two days of free admission — this Saturday, March 2nd, and Sunday, March 3rd.  On the 4th, we have a day of celebration,” he tells KYW Newsradio.  “We’re going to begin just before 10am with a very brief ribbon cutting ceremony on the front steps; we are expecting councilman David Oh.”

The museum is located at 19th South 22nd Street, and is open from 10am until 5pm.
