mod vintage Libbey roly poly bar glasses, prismatic crystal clear glass weighted bottom

Set of four paperweight bottom roly poly glasses, double old fashioneds, 12 ounce size (about 4 1/4" tall). These are Libbey glass, marked with the L. All four glasses are in excellent condition.

I love the hefty weight of these tumblers, and the way the glass bottom makes little rainbows everywhere. (Hard to photograph, but so pretty and fun!)
