Rare Washington DC Squat Soda from proprietor Ross & Otto dating back to the 1860s. Bottle is smooth base with the Ross & Otto name embossed on the front as well as the city Washington DC. The back is embossed with the capital letters R & O. This is a dug bottle with some of the cloudy haze typical of an old privy find. It does have a nice rainbow patina in sections and the embossing is pretty strong. The only damage is to the lip, which has some chippage on two sides and a small hairline vertical crack. Still quite a rare find, I’ve not seen this one on eBay before.
