Rare find, I have one copy of jogging A PHYSICAL FITNESS PROGRAM FOR ALL AGES, 1967 (C)  Bill Bowerman and W. E. Harris, MD.  Paperback cover is worn but in good shape without signs of tape or stickers having been removed.  Normal wear for the age with yellowing of the pages.  No missing or torn pages, no ink marks, or other blemishes.   Overall good condition and will ship in a padded, plastic envelope inside of a box for extra protection.
