There appears to be a man walking down the sidewalk. You can spot him (partially) just behind the truck's cab.

To the far right is a man sitting on a bench. He appears to be talking to a young lady standing in front of him while she is looking at the ground. And just above the truck, a young girl at the window. Playing or reading perhaps.

That radiator shape is unmistakable. Lots of lovely period details here, from the furled side curtains to the clamped on chain-brackets in the rear spokes and the single oil-fired tail lamp. And just to prove that fleet drivers never change, the rear fender has mysteriously found itself bent.

Looks like a circa 1920 White truck. Pictured is a restored truck from that era.
