This first flight cover was flown from Chicago O'Hare to Frankfurt in 1969 by Seaboard World Airlines.
The cover features a colorful airmail stamp with a denomination of 20 cents and is postmarked with a first flight cancellation.
The cover has not been graded or certified, but it is in used condition and would make a great addition to any aviation or stamp collection.
The cover is being sold as-is with no additional information on its condition.
