A very plain apartment block (as far as we can tell from the outside, the name of it is For Rent 2 & 3 Bedroom Apartments), but an attractive addition to the street nonetheless. The prominent bays, which would have been spurned by modernist architects, have two salutary effects. Aesthetically, they vary what would otherwise be a monotonous front. If you are the kind of modernist who despises aesthetic considerations, however, consider the practical purpose: bays like these flood the interior with light in a way that cannot be accomplished with any flat surface.
Addendum: According to our local John McSorley expert, this building was put up for developer John McSorley in 1903. The architect was J. A. Thain from Chicago.
