early antique Dr Scholl's advertising leaflets & wood foot massage tools in original box 1930s vintage

Very interesting early Dr Scholls product, a set of wood foot massage rollers in the worn original box, with some instructional and advertising leaflets (some older than this actual set). The paperwork is 1920s and 30s, with some really great old illustrations. It's so interesting to see how much (and yet, how little) things have changed in a hundred years. As certain as death and taxes, there will always be tired, aching feet.
