W.P Fuller Building, 1910
The "CBI Coffee Bean International" signs on the front and back of this building are fairly recent and cover the original signs, now unreadable. The W.P. Fuller Co. (paint and glass) occupied this building before, during or after occupying the adjacent Imperial Paints building so I'd guess these were Fuller signs.
Farmer Bros. Co. bought CBI in April 2007 and the building is for sale so this sign could disappear sometime soon. It's on the corner of NW Nicolai and Sherlock.
