This is an authentic vibrator used by women and their doctors in the early 1900's. It was believed to be a cure for hysteria... Fortunately medicine evolved. Excellent condition, working, professionally cleaned. Includes 5 original accessories and box. Device is electric, it has a Bakelite on/off switch and its head is nickel plated. Vibrator is signed "Hamilton Beach MFG. Co, Type D, Patented 24 June 1902, Racine Wisconsin U.S.A". The box is also signed "Racine" and is original. Cool museum piece and oddity.
