Stampfinder F01

First, compare the first character of the basic stamp. If you are looking for overprints on Chinese stamps, start with the China section first.

Inscriptions in Chinese characters could possibly be written to read left to right, or right to left. Therefore, both ends of an inscription need to be checked. And, like inscriptions in Roman letters can be very tiny, so can these, so have a magnifier handy.

There are many, many styles or fonts possible, so compare the general shape, make the closest match and go from there.
