Hi guys.
I think there's a flip side to the "is it real, or is it snide?" scenario.
I bought this from a friend about 12 years ago and he bought it from a reputable dealer in Mayfair, London. It has no provenance though, and I've never taken it out of it's frame. The Cross arms measure 18" x 18".
I'm fully aware that it might not be genuine, but as far as I'm concerned, seeing as though I'm never ever gonna sell it, I'm quite happy to believe it's the real deal and therefore have no real interest in having it authenticated.
I've posted it full size so you can scrutinise it if you want.

My own (optimistic) thoughts about it are that without a white border or background, and with that Autumnal looking camouflage behind it, it may be Austro-Hungarian?
Anyway, I just thought I'd put forward the "Sometimes ignorance is bliss" view?
Regards.
