Hi again, last night I showed one of the two stamps 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.   This is the other stamp in the set.  It shows a de Havilland DH.9A Patria II, the aircraft they continued their flight to Macau.
Oh, and since it has been raining here all day I have sorted more stamps and listed more in my Bidstart store, including some lovely Hong Kong Aviation stamps from 1984. Just search “Aviation” here  
 Hope you have a great weekend…. Michael
