The Manly Arts Course by World Champions

[olsport]

Sorry I don't have any pictures of this, but I am trying to get more info and a price range. I just acquired this. It is called, "The Manly Arts Course by World Champions". It is put out by the National Sports Council between 1955 and 1960. It has approximately 30 or so large 10 and1/2" x 14" booklets and heavy cardboard cards on different conditioning methods in correspondence course style. The huge 14 and 1/2" by 22 and 1/2" blue cardboard box looks very plain with white writing on the outside, but you open the hinged top and it has a huge black and white photo style print of Yogi Berra, Whitey Ford, and Mickey Mantle in Yankee pinstripes across the inside of the entire lid and red facsimilie autographs below.
Each card and booklet inside is for developing different muscle skills like a heavy cardboard card with Mickey Mantle says "Power Trigger" with a picture of him holding a broom to work on hands, wrists, and forearms.` Each heavy card and large booklet shows pictures of the following famous athletes teaching you there training methods: Joe Louis, Ted Kluszewski, Paul Giel, Kid Gavilan, Bob Cousey, Mickey Mantle, Gus Lesnevich, Doak Walker, Willie Pep, and Yogi Berra. This set comes very complete with a record album, enrollment certificate, sport selector wheel, and various other adds, and small booklets. There is some damage around the box cover's edge, where some of the cardboard is split in 2 or 3 places, which doesn't affect the inside cover picture.
Any info, auction records, and price range would be greatly appreciated!
