...most of it is plain and simple (like the Polish insignia that they painted on the nose of the 303 Sq aircrafts...)...
...but I liked this one enough to make its own little glory box for it...

The No. 71 Squadron emblem...Eagle squadron... 8-)
Its all hand drawn too...shading and everything...
...but I based it off of the 4th FG insigna (...what the Eagle squadrons eventually turned into after they were transfered to the USAAF)...as there are no good images of the orginal...so its probably alittle off...and they coloring is probably completely off (kinda hard to tell color from a black and white image...)...but as far as I can tell, this is reasonably accurate...

By the way, that flag was one hell of a job too, started as a flat 2d image, and "liquified" it until it kinda looks as if its flying...
