El Salvador Finding Guide

Today I received the following notice from Thomas Lera, Winton M. Blount Chair in Research at the Smithsonian National Postal Museum.

"The new Specialized Collections of El Salvador Finding Guide is now online. Five different collections of El Salvador make up this finding guide.
I want to thank Joe Hahn for the time he spent going through these collections in great detail and helping in the preparation of this finding guide.
You can find the guide http://www.postalmuseum.si.edu/findingguides/index.html"

Cheers.
