Could anyone give me insight on how to find the secret marks on Chinese Stamps.

I am try to sort some airmails at the moment C11 to C40 from 1932 to 1941.

I can't seem to figure out where these secret marks are located on the stamps.

Thanks

Dianne

Thank you very much floortrader

I don't know how I could have missed this as I must have looked at the stamps 100's of time over the last few days.

And thanks to you as well rogdcam

I always learn much from your posts

Your knowledge and contributions to this group is always appreciated.
