From a previous FAQFARM post: There are buildings remaining from
the Selig Polyscope studios at the intersection of Byron and
Claremont. The Selig trademark "Diamond S" is still over the
doorway of the loft conversion on the N.W. corner. The structures
now part of the used car dealer at Byron and Western were also
studio buildings. A series of underground tunnels still connect
them. There is a decaying tower atop one of the buildings, probably
used for elevated shots of the outdoor movie sets. Also see

list of movies filmed there (and at Essanay) see

There are numerous references in "Hollywood on Lake Michigan: 100
Years of Chicago & the Movies by Arnie Bernstein, Holly
Pluard". Selig bio at http://www.imdb.com/name/nm0783152/bio
