I have a set of Sky and Telescope magazines from Jan 1970 to Dec 1979 plus a bunch of duplicate copies for a total of 146 magazines. All are in very good condition, however the 1970 through 1974 issues have a name and address stamp on them and have a slight mildew odor. I will sell the whole group for $50 plus shipping. (Wow, that's only about 30¢ each !!) Thanks for looking.
