According to Eating in Translation, Thurston & Braidich, whose faded ad can be seen at 286 Spring Street near Greenwich next to what is now the Fire Department of New York Museum, was an importer of coffee beans and gum plants from Mexico and Middle Eastern countries. The main office was at the still-standing 27 Cliff Street just south of Fulton.
Because part of the brickwork has been repointed, the right side of the ad is a little difficult to discern.
