I am going through some of my late grandfather's possessions, and he has some interesting postage stamps and envelopes.

This posted envelope was slit at the right side and top with a letter opener to remove contents. 

Envelope is from the Libreria Voluntad, S.A. to the president of W.A. Sheaffer Pen Comapny in Fort Madison, Iowa.

Normal handling wear. Folding and tearing to top edge. Stamp is clear and in nice condition.

Postmarked 03 July1937 in Medellin, Colombia.

I will ship as soon as I receive payment.
