Klinger think?

I knew some railroads ran mail/post office cars under U.S. government contract, some of which were staffed to sort mail being delivered between cities. Some interurbans did similar things, with both dedicated and mixed mail/passenger cars.

But an obviously local two-axle passenger trolley bearing a U.S. Mail "badge", that's a new one on me, and the internets seem equally stumped, couldn't find any relevant references in an hour-plus of searching.

Is it an amusement park? If I could walk down a street in a Shorpy photo, I would check this place out!

Summit runs along the Maumee River through the heart of Toledo. This area of downtown has been prime real estate for a long time, and it has been redeveloped multiple times. The latest generation of buildings have large footprints and are meant to impress. You'd have to head up Adams a few blocks - to less valuable real estate - to see the older retail buildings similar to what's in the photo.

"Summit Street." In what seems to be the home furnishings district.

— and who would have guessed? Based on the banner farther down the street, they're having a sale!

The block at right would soon become home to the storied Toledo retailer; eventually it all burned (gee, guess you don't have to be a hotel to do that !)

The attractive building on the left, which ultimately housed a branch of Hudson's - yes, that Hudson's - kindled earlier:

Perhaps we should call it the "Tinder District".
