$1,234 · Wanted old photographs & postcards from China + Hong Kong

I'm interested in buying accumulations (small or large) of old photographs and old postcards from China, Hong Kong, Singapore and other parts of south-east Asia. Ideally, the photos and cards should predate World War 2, but I would be happy to take a look at and make an offer on material right into the 1950s. Postcards can be used or unused, but these and any photos must be in nice condition. If you have an accumulation of postcards that includes cards from other countries and/or other subjects as well, I may be interested in that material as well. Thanks !
