Postal Cover From China

Here is a very nice postal cover from Macau. I don't know if this is a complete set. If anyone would be able to tell me I would appreciate the expertise.

Enjoy the pic and Have a great day! Thank you in advance.

you do have all of the overprinted issues (1936). the original issues (1934), of which you have 2 of, is actually a large set of 21 values.

While the set of overprinted stamps is complete, what is not complete is the set of flight covers to and from Macau on this flight, of which this is just one. The total number in the set of Macau covers on this flight would be 9 different covers. They would be to and from San Francisco (you have the one to San Frnacisco), to and from Honolulu, to and from Guam, to and from Manila, and to Hong Kong (there was no Hong Kong to Macau leg of the flight). When collecting first flight covers the best kind of set to buy is one where all of the legs of that particular flight were prepared by the same person using the same size and style of envelopes and all being addressed to the same person. This first flight was covered by a very large number of stamp collectors who sent covers to be mailed on the various legs. The most common covers are yours, the leg from San Francisco to Hong Kong, the leg from San Francisco to Macao, and the leg from Hong Kong to San Francisco. As a result these particular first flight covers are quite common.

If you would like to collect first flight covers, most collectors do not care much about the stamps used on the covers other than to be sure the rate paid is the correct and exact amount that was charged for that flight. If a valuable stamp is found on a first flight cover most flight cover collectors will not pay any premium for it since they are focused only on the flight and rarely on the stamp unless the particular stamp was issued for that flight.
