One just never knows what can be found on Ebay. Some time ago, I found this Susanville Postal cancel for National Air Mail Week which was held during the week of May 15-21, 1938. It commemorated the twentieth anniversary of the implementation of air mail. Citizens and communities were encouraged to participate.
Of course, Lassen County Superior Court Judge Ben F. Curler an avid flier was more than happy to participate in carrying air mail. For a brief time, when Curler served as magistrate for Lassen Volcanic National Park he would fly to Mineral to hold court. Curler’s May 1938 airmail flight went from Susanville to Reno. At Reno, he picked up his father, Washoe County District Court Judge, Ben V. Curler. The elder Curler, was a pilot, too, having obtained his license in 1935 at the age of 70. The two flying judges departed Reno and flew to various Nevada communities as part of the National Air Mail Week campaign.
