Auction # 2423 ARGENTINA: Special auction for the end of the first semester!!

RARE RAILWAY PO MARK: Cover sent from Estación Tello (La Rioja) to Córdoba. On back there is a mark of traveling railway PO of Ferrocarril Argentina del Norte: "DISTRITO 9º - (F.C.A. DEL N. Nº1)" for 20/JUN, and another railway PO mark "BUENOS AIRES - SUCURSAL 2 N° 9" for 21/JUN (it carried the cover from Cruz del Eje to Córdoba), very interesting, low start!
