These stamps are on Rumsey Avenue just north of Michigan, alongside the Church of the Resurrection complex. There are one or two more E.R. Premoe stamps along that stretch besides these, but my hands were getting cold.

This stamp is on the front walk of the building rather than the public sidewalk.
The above stamp in context.

This is a plainer stamp than the other E.R. Premoe version, though the tradeoff is that it is easier to read. The date shows that the business continued on for a good while after the death of Earl R. “Lefty” Premoe.

The corner of Michigan and Rumsey. This is one of the buildings of the Church of the Resurrection complex.
This stamp is on the public sidewalk further north on Rumsey.
Another stamp further north yet, also alongside the Church’s property.
