The images below, part of Sociology 100, were provided by Ben Pierce of Kitchener, Ontario (Canada).
Ben reported that the Christmas picture was taken in 1985, but the other pictures did not have a specific date. Based on the size of the collection, and inclusion of Color figures, the last two pictures were likely taken in no earlier than late 1986.
If you would like to submit M.U.S.C.L.E. related pictures from your childhood, please email the pictures to the University of M.U.S.C.L.E.. An accompanying description to provide additional information about the pictures would also be greatly appreciated.
