I have not seen a Buck Brand bottle from Galveston, nor have I dug any of the San Antonio Buck Brand bottles in Galveston. The 1907 advertising is the only place I seen the Buck Brand stuff advertised in Galveston, and its also the first year I see it advertised in San Antonio. The embossed Buck Brand bottles I have seen always struck me as mid-Teens, not pre-1910, so I'm guessing that maybe the stuff was initially sold in plain unembossed bottles. Something to watch for though!
