Portland Oregon Postcard, c1935

"This view shows the Portland Central Bus Depot, the Y.W.C.A., Y.M.C.A., the Journal Clock, Meier and Frank (Largest Department Store on Pacific Coast), and the shopping district in the background."

It's also from before trees were invented. (And soon there won't be any more trees, so this view will be timely once more! :P )

"Angelus Commercial Studio. Portland, Oregon."

The vehicles suggest that this could have been the 1930s or 40s.

Enlarged to show detail.
