This 3.05 Pesos cover bears a single 5c Moreno and a single and horizontal pair of the 1 Peso. The single 1 Peso is a 1PNGR, and the pair of 1 Peso stamps is most likely from the clay paper printing (1PCL). This is a great combined usage of two separate 1 Peso printings. The cover is postmarked BUENOS AIRES-A.P. 6 on March 12,1945.
