These pieces are from Rosenthal's Studio Line in the Pirate Barware Pattern. It is blown crystal with an applied blob seal in smoke-colored glass, impressed with a design. The design on these highball glasses are a skull on one and a fish on the other. They are  3 1/8"" tall, and 3" across the mouth. They carry the sand-blasted Rosenthal etching (script capitol R with crown on top) on the outside bottom center of the glasses. I am listing several of the " old fashioned " barware glasses with different seals, and also a scarce lemon or ice bucket/snack container.
