The "St. valentine's day Massacre" wall-Does It Exist?

The famous massacre 9of the Bugs Moran gang by the capone gang0, is a part of Chicago history. i believe the address of the garage (something like 22001 N. Clark ave.) was torn down many years ago-what happened to the wall? i heard that somebody paid to remove and preserve it-is it in a museum somewhere? Any Chicago Dopers know?

And to add on to what Scruloose said, here is a link to the MyAlCapone website which shows all of the bricks and some history also.
