Named for its pressed block design, this Hocking Block Optic mug is one of the more sought after pieces in this pattern. There are horizontal rings molded into the glass forming four rows of blocks under the smooth rim of the mug. There is also glass in the center of the handle making this a solid handle.
This Green Depression Glass mug measures 3-3/8 inches in diameter, (add an inch for the handle) and 2-3/4 inches tall.
There is no mark. This pattern was made by Hocking Glass from 1929 to 1933.
There are a couple of nearly imperceptible nicks on the outside of the top horizontal ring.
