find an old building
Thanks for asking! Checked the city directories for 1945 and 1946; in both years, the property at 614 S 18 St is listed as Henderson Apartments. Other apartment complexes show up on the same block. It's a little early, but you can take a look at this 1937 map of the Kountze and Ruths addition to see some of the other structures around. At first glance I'd say the area was high-density residential with commercial/industrial areas just to the south.
