The first two pics are of an Early Glass mug from 1961-1964. This is one of the last mugs produced without a lip around the top rim. Sold The third and fourth pics or of a Late Glass mug from 1968-1974. Notice it has the lip around the rim and the ship is identified as the Grand Turk which sailed out of Salem in 1786. $17 shipped CONUS. Both are in excellent condition with no cracks, nicks or scratches. NOTE: I had badly underestimated the shipping cost, so I've had to adjust the price on the remaining mug. Sorry for any inconvenience.
