Where (and when) in Duluth?

This is kind of killing me. I already have two guesses that Google Maps has proven me wrong on.

But the apartment building is not, correct?

East Third St. & North 15th Ave. E ?

1952?

I was also going to guess 1952. I'll say 1951 instead.

RIJ, once you said the building and chimney were still there, I thought I knew where it was. And maybe I'm wrong  but it was the steeple behind the buildings. Looks like St. Paul's Episcopal Church. But I stared at today's imagine on google for a long while -- the trees obscure the steeple.

Early 50s. I'll go with 54.

1947.

The spruce tree has grown a bit.
