The caption on the back of this photo reads:
"1912-Shell's Seattle Dept. Westlake Ave. and Highland Drive. Site of present division office. Property acquired Sept. 27, 1912."
It's hard to get any detail in a 50 KB or under jpg image, but note the sign on the office to the left that says "American Gasoline Company".
The caption on the next one reads:
"1915 Show Place Shell station at Eastlake and Hamlin, Seattle gasoline was 12 cents a gallon, higher than the price of eggs."
