Vintage 1970s set of 5 tumblers

This is a listing for a harder to find glass set. There are five glasses , and they are an apple motif. These are the taller and thinner type of glasses. Great for juice, water, lemonade, iced tea etc. These measure 5.5 inches tall by 2.30 across. They are in great vintage condition, no chips or cracks These are also stamped but I am unsure of the makers stamp.
