This website advertises the charts that were originally in Joe's studio, http://www.pilates-studio.com/docs/store/archcalendarsale.htm, and he may have been the model in the poster's. Historically that is pretty interesting and of value to any pilates studio, they are very reasonably priced for anatomy posters, there are five in the series.
