Take a look at the pictures and don't hesitate to send me any questions. I will do my best to answer them.  This item has been kept in a smoke free home and protected from wear and tear. This is among many philatelic items that my father in-law kept in his extensive library of stamp collecting. I will be going through his entire collection of stamps and stamp collectibles over the next few months to list the items that I believe all philatelists would love to have for their own collections.  Please don't hesitate to make an honorable offer.  I will be glad to review those and respond in kind.  I would be honored if you put me in your saved sellers list and check back frequently as new items will be listed.  Thanks for looking and God bless!
(shipping and handling)
I will ship both domestically and internationally.  Please wait for final invoice for shipping internationally.  That will be new to me and I want to make sure and get the items sent the most economically and efficient way possible.
