This sheet is approximate 15 X 7 Inches, published by Ministerio de Comunicaciones, Direccion de Correos, dated April 15, 1955. It reads: EMISION DE SELLOS DE CORREO PARA CONMEMORAR EL "CENTENARIO DEL PRIMER SELLO POSTAL" 1855-1955. Very nice piece, very light spots. The 15 inches side is folded im three parts, in one side of the sheet is a history of the emission in three languages, each fold has the history of the issue in a different language.
The other side of the sheet is shown in the image, only two folded sections are shown, all three parts would have been too large of an image to show.
Only a few left in stock, order now before it's sold out for good. Once a rare collectible is sold, you may never come across it again.
This makes a great gift, or for another upcoming event.
Esto seria un gran regalo, o para otra cercana fecha señalada.
