Philadelphia: Vail Brothers, [188-]. Stiff card, slightly larger than 4x6.25 inches, with Powderly's portrait (a sepia photograph from the negative) on one side and text about Ideal Tooth Powder and Ideal Quinine and Sulphur Toilet Soap on the other. Plate measures 3.5x5 inches; his moustache about 1.3 inches from left to right twirl. Very good.
