PLEASE READ THIS DESCRIPTION CAREFULLY!!!….Nice lot of 25 unused US postal stationery envelopes with the pre-paid postage of 1 1/4 cents. The envelopes measure 6.5″ x 3 5/8th». I found a website that described these as «..Catalog U541 Franklin Envelope Die 1 UPSS size 9..» and stated they were printed in 1960. I went through quite a few while I was counting them and I did not find any that had stuck flaps from the old adhesive. Actually these are in really nice shape. Features the image of Benjamin Franklin embossed on the top right corner.
