Waterlow & Sons Commemorative 1949

I'm looking for information on a 1949 Republique D'Haiti Bicenteniare International Exhibition 10 centime stamp.

Anyone?

Thanks~

Scott only lists 3 stamps issued in 1950 -- a 10 centime Coat of Arms for the 200th anniversary (in 1949) for the founding of Port-au-Prince, and two airmails (30 centime Columbus and 1 gourde Dumarsais) for the same event.

None of them are worth over 50c. No stamps were actually issued during 1949 except 8 different colors of identical 5c Postal Tax stamps showing Washington, Dessalines, and Bolivar.

You must be referring to Scott #384, which, as Doug2222 said, was issued in 1950, but celebrating 1949. It was printed by Waterlow.

But #384 seemingly has nothing to do with an Exhibition?

It seems the exhibition went on into 1950?

Yes, but there's nothing on that stamp about an Exhibition, just the 200th anniversary of the capital, Port-au-Prince. The OP may have the stamp on a cacheted envelope, or a commemorative postmark.
