Stamp collection fist issue airmail .100 plus

From 1905-to about 1955.with many war time stamps .also pre-war from the US..Germany. Poland Asia Amsterdam and France ,Africa. And around the globe of fist issue stamps.. first -flight issue with corresponding first issue envelopes from around the world. Some envelopes are still sealed. Many have letters inside or company letters. Lawyers and tax letters many interesting correspondence. A few of these stamps are quite rare :due to the fact some countries where they are from don't exist any longer .This is a really nice stamp collection knowing they are timed stamped dated and beautiful shape..fist issue fist flights in some cases .Hard to find stamps .not torn of a random envelope. You know here it's legit and yes some sought after . This is a great collection I actually do not collect stamps but obtain them in auctions from time to time and actually have sold them on this same platform with great buyer satisfaction.
