Thanks for sharing! These stamps were printed on a very delicate rice paper that I always afraid they'll crumble in my hand.
You correct. The non surcharged stamps were issued in 1948 for use by the Viet Minh forces. Your fifth stamp is a Service stamp, surcharged 0.1 Kilo Rice and issued 1955. Your last two stamps are surcharged 50 Dong and issued in December 1956. I enclose a copy of Michel catalogue with a lot of information. I hope it is OK to post one Catalogue images, if not, mods, please delete it.
