Worms Am Rhein Wine Tasting Glass. A Clear Glass with Wappen Von Worms Coat Of Arms. The Front of the Wrap shows the Colorful Dragon Themed Coat of Arms. Back of the Glass shows measurement levels in Black. Actual Glass is about 2 3/4 inches tall and about 1 3/4 inches in diameter at Rim. I find no markings on the Bottom. No Chips or Cracks with All Colors Strong and True.
