1926 Madrid to Manila Flight Souvenir Cards Card Front Two used souvenir cards of the Madrid - Manila flight in very decent condition. Great addition to any air mail collection most especially now that non flown items can be included in aero competitive exhibits. At an average of $50.00 each, smart and cheap purchase by my friend Ed Nocom. These cards are not easy to come by now and I was really expecting the closing price to be much higher.
