wolfey this is a fragment but I was wondering how old it would be by looking at the picture. very thick clear/green glass. it has the Washington monument and says ''trade mark restricted'' on what I have. thanks
Chris Beer for sure. Collectors would call that aqua (aquamarine) color. See this link http://www.oldbreweries.com/breweries-by-state/maryland/baltimore-md-115-breweries/monumental-brewing-co-md-72b/ for info on this brewery.
