My great grandfather John Stirk's Art Glass shop - 18 Sutter St, San Francisco May 1905
My great grandparents owned this glass emporium in San Francisco at the beginning of the 20th Century. It was destroyed in the earthquake of 1906, and they moved to Los Angeles, where my grandmother met my grandfather when they were children.
So I guess without the earthquake I wouldn't be here!
Notice the Burlington Route calendar on the wall, I compared to a 1905 calendar and I believe it is for May, 1905.
Just found online a 1905 San Francisco phone directory, showing a J F Stirk, running 'AGT U S Glass Co' at 18 Sutter. So at least now I know where it was!
