Souvenir sheet issued by Casa de Moneda de Chile for the Valdivia philatelic exhibition, including the stamp Sc.269 and logo of the Montreal 76 Olympic Games and Argentina 78 Football World Cup, etc., with MUESTRA overprint and "000" numbering, excellent. Along a "normal" sheet with a tiny natural defect of the gum, very interesting! (Image)
