The larger mug is 3" tall and has the initials U.I.T, 1904. The miniature mug is 2" tall and has A. Mercer 1904 etched in gold lettering. Both are antiques and show wear from age. The larger mug has a chip in the handle with a piece missing piecing at the bottom of the handle and it is cracked from the missing chip around the handle. We obtained this item from an estate sale among many other antiques.
