Alfonso XIII – The "pre-issued" 1929 Express stamp

The 1929 recess-printed express stamp was "pre-issued" in a total of 18.000 copies as part of the overprinted commemorative set for the 55th reunion of the League of Nations in Madrid. The express stamp was surcharged with a typographic overprint in blue "Sociedad | de las Naciones | LV reunión | del Consejo | Madrid." The set was valid only seven days (June 10th - 16th, 1929) and was sold only in the main post office (correo central) in Madrid and in the branch post office of the Spanish senate (senado) which during the reunion was the official branch for all participants.
