Hard Rock Cafe Niagara Falls Shot Glass. Tall Style. Front of Clear Glass shows the Colorful Yellow and Red Hard Rock Cafe Logo. Beneath is Niagara Falls in Red. Back of Shot Glass is Blank. Actual Shot Glass is About 4 Inches Tall and About 1 1/2 Inches in Diameter at Rim. I Find No Markings on the Bottom of the Shot Glass. No Chips or Cracks with All Colors and Print Strong and True.
