ad53 Portland OR workers construct Northern Pacific Railway bridge 1908 / labor For Sale

I don’t have the book Bridges of Portland by Ray Bottenberg, but l have included an online image from page 56 in order to show that my photo postcard depicts driving the last pin in the Oregon Slough Railroad Bridge on June 25 1908. The book says the bridge was a swing-type drawbridge designed by Ralph Modjeski for the Northern Pacific Railway (NP or NPR). My vintage original real photo postcard was printed at the time — the deltiology section of the Playle website says the AZO stamp box is known 1904-18. Approx 5 3/8” x 3 3/8”.
