China's third airmail issue of 1932-1937 

This stamp during the hostilities between China and Japan was printed in Hong Kong, from 1940 on watermarked and unwatermarked paper.

From 1932-1937 the printing was done in PEKING, perforated gauge 14 while Hong Kong issue are perforated gauge 12 to 13.Peking gum is yellow, thick and bright.Hong Kong is white, thin and dull.Also to make the difference it is a secret mark on the first chinese caracter after the denomination on the bottom .

To see the difference I recommend

Excellent site to keep as  reference.

This vertical block with overprint error, is HONG KONG PRINTING.


FOR SALE trough this site, on demand and with a reasonable offer.
