RARE ROUTING and good marks: Cover sent from SAN SEBASTIAN to Germany on 10/OC/1945, IT WAS CENSORED AT ORIGIN, it arrived in Madrid on 12/OC where it received the violet marks "SIN COMUNICACION CON EL PAIS DE DESTINO" and "Devuelto al remitente". The sender had indicated on back an address in Brazil, so it arrived in Rio de Janeiro on 6/JA/1946, very interesting! (Image)
