I absolutely love vintage pictures and engravings of disciplinarians in action. The fashion might change but people's thirst for power exchange does not.

I found that little Jewel on youtube."Dressage au Fouet", a remarkable, rare, purely fetishistic film  of a mistress disciplining her slave. Made by Jacques Biederer (Ostra Studio), a Paris photographer of high-class erotica. In the '20s & 30s he made elegant (and humorous) "French postcard" type nudes - and incredible fetish pictures (spanking, whipping, S&M, pony play, etc.).
