antique embossed measure glass medicine dose cup, Adlerika quack remedy bowel cure

Antique or near antique vintage dosing glass, with embossed measure marks and advertising for Adlerika Natural Bowel Cleanser laxative.

Shot glass size, holds one ounce and stands about 2 1/8" tall. Kind of unusual, I've never heard of Adlerika before! Doesn't look as though it was used much, if ever - this glass in very good condition.
