This is the one! A Full Bottle of Vintage ENGLISH LEATHER All-Purpose Lotion, from the Mem Company, Inc.
Original four ounce clear glass bottle with 'MEM' molded into the bottom. It has the distinguished large light-wood cap, and reddish wooden box with box-joint joinery.
The bottle is filled to the brim with that recognizable reddish-brown full-bodied magic potion.
The labels on both the bottle and box show the hallmark's details of the helmet, saddle, and crop, on a textured brown leather background. [The photos show the actual item for sale.]
