Good to see there's still some room left on the walls... I checked my stash of 'artwork', drawings mostly, Beaufighter, Mossie, Spit, Hurri, even a watercolor of a Camel in a clouded sky! (No, not like the famous 'mossie at night' - see below -, not 10/10 white clouds!) and will bring a selection over.
Mind you, they aren't really originals, most were drawn from existing pictures, though with sufficient artistically justified freedom (also known as 'errors')
Beaufighter, after it's already been packed for transport, picture taken with mobile phone ... the packaging makes it look a bit rougher than it is, and it bit brownish... though it is roughly drawn / sketched
'Mossie at night' (by an unknown artist)
(Are we there yet?)
