re: Philippine VON gronau C-31

Probably a collector's "mark". Back in the day many collectors had small "owners stamps" made up to stamp the back of stamps added to their collections. Similar to and serving the same purpose as bookplates that people put on the frontispiece of books in their library.

re: Philippine VON gronau C-31

Given the overprint, it is more likely an expertiser's mark. There are sites on the internet that list ("catalogue") expertiser's marks and identify some of the most important ones through history.

There was a previous long discussion of expertisers' marks earlier this month on this discussion board. Maybe somebody can find it an add a link -- I am being called away from my desk right now.
