MCM ridge waisted ships drinking glasses, heavy bottom highball glasses, double

...old fashioned whiskey glass A set of 3 heavy glass bottom drinking glasses, possibly ships drinking glasses, as it will be near impossible to knock these over. With a ridge waisted design, and thick glass foot, the sides are a regular thickness with a subtle curve to the top half. These are unmarked for a maker, but look most like the designs of Magnor Glassverk (Norway) from the 1970s. They are in great vintage condition with only small marks of age and use, no chips or cracks. You will receive all 3 glasses. Size: 5-3/4 inches tall (14.5 cm)
