In 1922 Roald Amundsen departed from Seattle for Alaska on the steamship MAUD. On boards was as Junkers J13 airplane in which he intended to fly over the North Pole to Spitzbergen. The plane crashed on a test flight ending the expedition. North Pole stamp collars in the same colors of the U.S. 1¢ to 4¢ postage stamps of the period were issued by the expedition in sheets of 9. These were to placed on the envelope and then the postage on them. The center collar had an error with ARI instead of AIR. Two unused collars are here along with two flight covers AAMC 1021. One bearing one complete set of collars with stamps plus an extra 2¢ value with the original June 3rd, 1922 dated cancel and North Star Air post markings. The four cent value is in the error "ARI" collar instead AIR. The other cover is franked with a single 2¢ value with the July 28 Nome Alaska cds, the MAUDEXPEDITION rubber stamps and the North Star marking. Great pair of covers. Suggested bid $400
