I still have the Strength and Health, and Ironman, and powerlifting USA mags for the 1970's and 1980's. I they are all packed and sealed. I have no idea what to do with them? Maybe I should sell them. They only cost like 60 and 75 cents back then.
I sold off a bunch of mine when I needed the space. If I could do it over again, I'd buy a decent scanner, and scan then sell them. The older issues go for pretty decent money, and things like Arnold, Louie, and Cory Everson covers can sell surprisingly high.
I keep hoping that someone will buy the rights to the old issues, and sell downloadable classic issues or sets like some other types of magazines are doing, but no such luck.
