Hi, well a lovely day here, and I had time for sorting stamps and a visit to the Stamp Arcade in Mong Kok. A very enjoyable day.  I found this lovely corner block in one of the dealers stock books.
Issued in 1999 to commemorate the 75th Anniversary of the Portugal to Macau flight by Captain Sarmento de Beires and Commander Brito Pais in 1924.   They departed Lisbon eastbound in the Breguet 16.Bn2 Patria, shown on the stamps, beginning an attempt to fly around the world but crashed in India and continued in a de Havilland DH.9A Patria II before being forced to end their attempt in June in Macau. 
Tomorrow I will show the other stamp from the issue that shows the de Havilland DH9.

Have a great weekend…. Michael
