Jack Kramer Pro Staff, Autograph, and Pro Model

Tennis with wood rackets is more fun than with the giant-head high-tech ultra-light, ultra-strong, carbon composite rackets everyone uses now. If you never learned to play with a wood racket you won't understand. 68 square inches is big enough. (Racquets bigger than 95 sq inches are for beginners, the elderly, and people with no shame.)

Wilson's Kramer ProStaff and Kramer Autograph, along with the Dunlop Maxply were some of the great rackets when tennis changed (not for the better) pretty much with the introduction of the Prince Fat-head racquet and similar ilk (present-day, Babolat's toy racquets on steroids).
1940s to present
Old-school graphites (all under 90 sq in)
