Fraternal Shaving Mug with the simple version of the symbol for the Jr. O.U.A.M Fraternal Organization (Junior Order United American Mechanics), because their symbol has the compass and square that is the same as the Freemasons, this is occasionally confused as a Freemason mug, however the arm with hammer inside indicates Jr. O.U.A.M., a “G” or nothing in the middle is a Freemason symbol.
