CANCELS OF MENDOZA: Cover sent to Luján de Cuyo on 23/NO/1916, with the very rare cancel "ESTACION MENDOZA - MENDOZA" in blue, as the addressee could not be located the cover was forwarded to Luján (San Luis) and from there returned to sender. On back it bears several interesting postal marks, some very rare, including one railway cancel. With opening defects, but interesting piece for the specialist! (Image)
