The stamp depicts a modern jet airliner and was issued to meet the new domestic airmail rate that took effect that year.\u003c\/p\u003e\u003cp\u003eThe early 1970s marked a period of transition for U.S. airmail service as rates adjusted and the Postal Service increasingly relied on high-speed jet aircraft. Coil stamps like this one were produced specifically for vending machines and automated post offices, making them an essential part of everyday postal operations.\u003c\/p\u003e\u003cp\u003eA notable detail is the Artmaster cachet’s stylized winged figure above a rounded tablet that explicitly labels the issue as the “ELEVEN CENT United States AIR MAIL Rate—1971 COIL,” a design choice that directly references the rate change and format. The cover also carries the printed “FIRST DAY OF ISSUE” inscription beside the stamp.\u003c\/p\u003e\u003cp\u003eCollector appeal is enhanced by the combination of a transportation-themed jet stamp, a clearly legible first-day cancel from the official city, and the attractive Artmaster cachet. The cover remains in fresh condition, making it a strong addition to any U.S. airmail, coil, or 1970s topical collection.\u003c\/p\u003e","brand":"Maple Springs","offers":[{"title":"Default Title","offer_id":51392036864164,"sku":null,"price":5.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0580\/4713\/5908\/files\/20260629141147.jpg?v=1782776020","url":"https:\/\/maplespringsllc.com\/products\/1971-us-air-mail-coil-11-spokane-wa-first-day-cover","provider":"Maple Springs","version":"1.0","type":"link"}
