No, it's not Bluffton. It's Main Street Ada. You'll find the Brewer Block on the east side of Main, directly across from the Ada railroad depot.

When this photo above was taken, the stately Brewer Block was home to the Ada post office. The street was bricked, the Pennsylvania Railroad had a double track through town, street lights were relatively new, windows were more expansive and a taller building stood where Cole's car lot is located today.

Compare the earlier photo with the 2020 version below. The building has remainly relatively unchanged over the many decades since the top photo was taken.
