Royal Palm Hotel, 1913
A decade ago only the single word "drink" remained of this sign on the side wall of the Royal Palm Hotel at the corner of NW 3rd and Flanders. That word has since been scrubbed and the original sign at that spot, due to deterioration, is lost forever. I suspect it was a Coca-Cola sign because of the little Coke-esque curley-cue at lower right and their early 20th Century slogan, "Drink Coca-Cola.".
Not much left to see but take a look next time you're standing in line for the Portland Classical Chinese Garden.
