Design looks like a vintage Spalding racket but the brand label is missing. Spalding introduced the first aluminum racket in the late '60's.

　　Standard head size allows more ball control, develops more hitting accuracy, & off-axis hits require less hand torque than oversize head.

　　13.1 oz. aluminum racket transmits less ball impact stress to the hand, wrist & arm and may also provide more hitting power than lighter weight carbon/composite rackets.
