This antique, shot glass shaped, medicine dose cup is in mint condition. It has embossed lettering on the front, advertising, "J. C. Griesemer, Prescription Druggist, Corner of Ninth & Penn", which is in Pittsburgh, Pennsylvania. There are embossed (raised) graduated marks on the back marking the dosage. One line is marked, "TABLE", the next is marked, "DESSERT, and the last is marked, "TEA" for teaspoon. It's smaller than a shot glass, measuring 1&3/4 inches tall, by 1&1/2 in diameter across the top. Late 1800s-early 1900s.
I currently have other medicinal renovators in my shop, some with advertising, and am happy to combine shipping. To see them all, type, "renovator" in the California Girls search box at the top of the page.
