As described in the title line a First Day of Issue envelope and a matching information page.  Lots of historical information printed on the page.  100% fresh and without fault. ======= The First Day of Issue is a long practice in the stamp collecting field that collectors desire for the stamp issue postmarked on the first day that the stamp is available for sale to the public and released normally in just one city as seen in the postmark.  Page size 8 X 9.75 inches, great to mount in a frame and hanging on the wall.  I do have duplicates of this item, and each will have a different name and address, but all neatly typewritten as shown in the image.  Shipping via USPS large envelope which will cost $2.00.
