Going through our archives is always an interesting experience. There are the well known names, books, courses etc of course, but we often run into other items which are rather mysterious. This 1909 advertisement would certainly fit that bill. Can’t say that I’ve ever come across Dr. S.C. Hall’s name elsewhere. Build strength by lifting weights? Pfftt-that’s for the birds. Dr. Hall’s Electro-Vigor machine will “send glowing, electric fire coursing through your nerves and vitals.” Where do I sign up?
