I like the look of it as well. Do you collect Dutch East Indies postal stationery?
I would expect this to be listed in the Higgins and Gage catalog, but I do not have that particular volume that includes the Netherlands Indies. They do have it at the American Philatelic Society Research Library. You can contact them directly and they will photocopy the relevant pages and email them to you for a fee. The fee is much reduced if you are a member of the American Philatelic Society.
Here is a link to a recent
ebay auction for the 10 cent variety that has been used. I do not know the relative rarity of the 10 cent denomination compared to the 22 1/2 cent variety, but often used examples of postal stationery go for more than mint ones. Anyway, this one sold for $9.99. Here is the link.
