This is a first day cover from 1946 with a 3c stamp depicting the U.S. Merchant Marines in honor of their service in war and peace. The cachet features a picture of the merchant ship supply line and is certified with an L W Staehle cachet FDC. The stamp is in F/VF (Fine/Very Fine) grade and has a multi-color design. The cover was cancelled on the first day of issue and is a great addition to any collection of United States stamps or covers.
