Welcome to Cortland Covers!
My name is William Thoman and I have been a dealer in U.S. Stampless covers since 1974. My stock includes both handstamp and manuscript postmarks and I hope this site will provide you the opportunity of adding new stampless material to your collection.
If you enjoyed using my site, please add it to your bookmarks. If you have
stampless material that you
would like to sell, please contact us.
