This 7 lesson course was copyrighted in 1957. Each lesson had a different famous body builder of the day featured on the front cover of the lesson. The 7 body builders were: Irwin Koszewski, Doug Strohl, Reg Lewis, Jack Lalanne, Clancy Ross, Jack Delinger and Leo Robert. Pictures of each exorcize being done by the featured body builder were in the pages of each lesson. The outside binder has a couple 1-2" rips front and back, is tattered and has stains, but is all there. Only the 1st course is missing most of the back page and has come apart from the binding as shown in the last pic. All other course lessons are complete. There are pencil markings of the number of repetitions marked inside near each exorcize on all lessons. I did not try to erase them. As you can see in the 2nd picture, this even comes with some literature promoting other offers at the time. The mailing envelope is dated 2-17-58. I hope I have described this accurately enough. If not, email me with questions. I can also take more pics if you would like.
