monumental bottling co. ?

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

Beer for sure. Collectors would call that aqua (aquamarine) color.
