Collinsville, Illinois. Built in 1949 in this former catsup company town, the World's Largest Catsup Bottle celebrated its 65th anniversary in 2014. It's the water tower at the old Brooks Catsup Plant and headquarters.
The bottle glass is brown and has a conical neck. The most widely used sizes are pint (568 ml) and half pint (284 ml). There are also quart (2 pint) and nip (1/3 pint) sizes available. The barley wines used the nips while the Midlands breweries the quarts.
