Martin, Jr., was an avid tennis player since his days on the Norte Dame tennis team in the 1940s, a team which included Chris Evert's father. He got me interested in tennis when I was in my teens and for years we would play on Sundays with my sister and brother in law at the Mission Valley Tennis Club which was just recently torn down.Three of the six racquets in the photograph are "hand me downs" from my dad and upon reflection, I've never have bought a tennis racquet for myself.Tennis racquets show the rapid increase in technology since my childhood.When I was young, the only racquets were wood as represented by the Spalding "Doris Hart" model racquet on the far left which I obtained for free at a garage sale.
