Set of 2 Pyrex Tableware mugs, #709, with the gray Grecian design and hold 7 ounces. This Floral Dinnerware line was available between 1959 and 1986. The mark "Tableware" on the bottom dates these from no earlier than 1964.
These two mugs are in great shape with minimal wear. They work great with coffee, tea, or even whiskey! They are tough and can withstand a lot, being specifically made for restaurants and diners.
