No, the first appearance of the Superleggera seatpost was in the Catalog #16 Supplement dated November 1971.
From the Campagnolo Timeline at http://www.velo-retro.com :
"1971 -- Catalog #16 Supplement is printed in November for the year-end trade shows. The Superleggero pedals with black anodized aluminum cages, Superleggero seat post (no flutting, thinner wall, aluminum support cradle, drilled pivot, originally with engraved graduated scale), and plastic Superleggeri pumphead are introduced. The patented toothed washer (rondella dentata) is introduced for the Record sidepull brakes, along with the steel Gran Turismo rear derailleur, Velox low-cost derailleur, Elefante control lever, and the steel three-pin Sport cotterless crankset. The allen seatbinder bolt is introduced."
Incidently (ahem)... this supplement is reproduced in the Catalogo Campagnolo book that covers 1953 to 1984 available from Velo-Retro.
