Antique Ladies Victorian porcelain Shaving Mug

This darling Antique Shaving Mug “Forget Me Not”, has flowers and leaves and gold writing. It measures 3-1/8” tall and wide. It’s very old and I don’t see and cracks, but by the top rim the green paint has a flaw. I can just picture a lady back in the 1900’s getting ready for a date and using this mug to shave her legs.
