Circa 1920s, this is a shot glass shaped dose measuring cup with embossed lettering on the inside of the glass. It measures about 2&1/2 inches tall by 1&3/4 across the top. It is in mint, like new condition.
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.
If you are ordering more than 1 item from my shop, wait to pay until I send back an invoice with the combined shipping discount.
