Paging Gistok and/or other movie theater fans.

According to my research the Crystal Theatre, which was on the north side of Michigan Avenue at 31st, was actually the second Crystal on Michigan Avenue. The first Crystal, on the south side of Michigan, was razed when Michigan Avenue was widened by 120 feet in the late 1930s.

I would like to know the address of the original Crystal and its years of operation. I'm also curious as to why the Kramer Theater, just down the street and also on the south side, was seemingly unaffected by the widening.
