Actually, Stanley says (in his South America catalogue) "A set of five postage and five air stamps showing the flagship of Columbus was issued by the Sociedad Columbista Panamericana in October 1935 but their status as postage stamps is doubtful".
I also have a couple of stamps from a Cuban series, of which Gibbons says, "In 1935 a set of stamps commemorating Columbus was authorised but cancelled when the shipment from the Spanish printers was delayed. The stamps never had franking value in Cuba".
