Description:

1919 (April 4) Manila Exhibition Flight Aero Club of the Philippines flimsy 'AERIAL POST CARD' with photo of the pilot Miss Ruth Law on the reverse, Philippines 2c tied by large triangular 'THE CHAMPION EXPLORER OF THE SKY/...' cachet in violet, tiny corner defect but remarkably fine for such a fragile item. Only the few cards actually flown were cancelled with the triangle cachet. The many souvenir cards released the next day were cancelled with a standard postmark.
