I have some old San Francsico newspapers from the late 20's to mid 40's. They have classified ads in some of them. I will look at them when I'm not to swamped with work. Bud, gave me one of those GTC chips to try to find info on. I looked through the Crocker Langley(1929) directory and could not come up with a match. I looked through names of people, companies, and clubs.

Cigar manufacturing/retail
Goldsmith and Castillo...628 Montgomery st.
Gus Carlson ................2100 1/2 3d..(3rd st??)
Geo Clark...................486 Ellis st.

The Clubs
Germainia Club......605 Polk st. (Shared with Rod and Gun Club...605 Polk) interesting?
Girls club..............362 Capp st

Grocers
Giovanni Canata .........1199 Columbus
Girolamo Castagne......1261 Stockton
Geo Choulos...............1237 Polk st
Gus Contos................3838 California st

I am still trying to look into this, but had been on the back burner for awhile.
