IC Rapoport is one of the photographers who took pictures of Joe Pilates. You can see many of them here: gallery.icrapoport.com/
To support the lawsuit that'll ensure that photographers like IC Rapoport keep copyright of their work, please support the Pilates Transparency Project via linktr.ee/pilatestransparen... (there are some other goodies on that link tree - like more info on the March MATness classes - hence I am linking to it...)
Here's a screenshot of one of Rapoport's recent posts on Facebook: facebook.com/photo/?fbid=59...
