I was looking through a stamp collection that I found in my Mom’s home when I cane across this. As far as I can tell, it says something about the postal service of central China on the top and the bottom writing is just “5000 yuan”. There is however no date on it at all. Since this is written in Traditional Chinese and talks about central China (not Taiwan or Guangdong where Traditional characters are still in use today afaik), I think it might be pre-revolutionary.

As for the guy, I can only really think of Sun Yat-sen, but it doesn’t look quite right to me. Does anyone happen to know more? Does anyone recognize the guy?
