This came from the Avondale Sunday market as well. It was inside a shabby looking frame, but it caught my eye (as things can tend to do).
It is a postcard (says so on the back). Parts of the text at the back have been removed due to sellotape (wretched stuff), but it's something about ACTIVE SERVICE, No. 76 something-or-other Army Series, and G.P. & S. L.
"Vedette", means a mounted scout or sentinel, near as I can find out -- but is it just a description, or the artist's non-de-plume?
Not really NZ history -- but I do like the artwork. Suggestions/answers always welcome.
