Hard Rock Cafe Shot Glasses. San Francisco. Tall Style. Set of Two. Front of Shot Glass shows the Hard Rock Cafe Logo in Red and Yellow with Black Print. Back of Shot Glass is Blank. Actual Shot Glass is Just Over 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 Strong and True.
