OK, this post sort of does Double-Duty, it's a grey chip marked (I think) Sill's. Supposedly from the S.F. Bay Area but nothing more known about it. Anyone know?

Reverse side says . . . something else . . . too worn for me to discern. I tried Googling . . . "Geraniums look good on San Francisco Window Sills." Thank you for that, Google. "Major Taylor was at Fort Sill, Oklahoma Territory, in 1906." Lester Sill, producer for the Go-Go's. Good work on that, Lester!
