My father is the current holder of the mug, but when I started on my path of traditional wetshaving, he passed it on to me. Anyone know anything about these old mugs? I'll be seeing him (and the mug!) tomorrow, and will see if there are any markings on the bottom or anything. Legend has it that its my Great Great Grandfather's, and it's funny to note that my last name is spelled on it with "Mc" instead of "Mac"
