This stamp on the east side of South Clemens Avenue between Michigan and Prospect is small and indistinct. I suppose that’s why I have evidently overlooked it many, many times; this is a block I walk often and yet I don’t remember noticing it before.

The date seems to be 1952, but the name is a puzzle. I am pretty confident it is _ _ G L _. I also think the first letter is R, or maybe B, and the second letter looks like an E. What do you think?
