Once again I'll try to date it purely by clocks.
On the left we have two clocks. Just next to the streetcar is a dark clock, owned by L. L. Moore. We saw this clock recently down at 2nd and Cherry in front of the Hoge Building. When the Hoge was destroyed in 1909, Moore moved up here in front of the Leary Building between Spring and Madison. He was here until 1913, when he sold his business to drill for oil in Ballard. Albert Hansen moved in here at that point, eschewing Seattle's jeweler origins down at 1st and Cherry for the swank push up 2nd.
So we've got a bounding range, 1909 to 1913.
Next door to L. L. Moore is a clock spot that is new to me. It seems to have been owned by Louis Hoffman, 1016 2nd - he's the only jeweler I have in this spot in this range, and only for one year in 1911.
1911 is my guess. Perhaps a year earlier?
This is really exciting for me. In the 6 cards that I've posted in the last week or so, I've found 3 new clocks (or new location/owners of clocks). I now have 637 pieces of "evidence" of a clock in a location at a specific time in Seattle.
