To continue, the brown, 1.5-Penny, British definitive is in great shape! The S.O.N. CDS from the F.P.O. is superb!
Lastly, as for the envelope, itself, it is in very good condition! It's very clean. Outside of some creases in it here and there, there is very little wear and tear on it. The back flap is intact. All things considered, this cover is a neat, uncommon piece of British military postal history from a soldier serving abroad in Tientsin, China, in 1930!
