654 7th St
This building and the adjacent one to the north, 650 Main St, have unique hexagonal window cutouts - since filled in with normal square windows - suggesting that they may have once been a single building, perhaps a commercial one. The roof of 654 is very different so either it has been altered or the two buildings were not one. The stepped roof line of 654 adds an unexpected decorative element.
It is possible that this address is actually 654 Main St, but the entrance and house number are on 7th St.
