The pictures show views of all (12) Old Unused UnitedStates Stamped Envelopes in this lot. The first picture shows all of the envelopes and the second picture shows a closer view of all of the embossed stamps on them. The top left two are pages you would write on and fold to mail. These range from one cent to eight cents. All of these for one price! To judge the sizes the largest two (air mail) measure 6-3/4'' x 3-3/4''. These appear to be in very good to excellent condition as pictured.
