I acquired this cover from an old dealer stock.  It was originally priced at $40.00 in the late 1990's.  This is a first flight cover featuring the 8-cent airmail, Scott #C4, paired with the 2-cent Scott #627.  The cover has a great cachet showing "First Flight Medford Oregon" and is postmarked Medford, Oregon, SEPT 15, 7:30 AM".   The "From" indicates Medford, and the "To" Portland.  Another postmark indicates "Seattle-Los Angeles Route - Medford, Oregon, 7:45 A.M. SEPT. 15, 1926".  The reverse side shows a Portland, Oregon, cancellation same-day; and a return cancellation to Lockport, PA dated SEP 20, 1926.  There is a small corner repair (lower right corner) to the C4.  Scott Catalog value for the C4 on a regular cover was $22.50 and for the #627 on regular cover, $1.00 in the 2015 catalog edition.  We are offering this great cover at $20.00.
