I was thinking more of the pin-ups who were probably painted by hand. I suppose ground crew who were maintaining the planes during the war managed to find the time and an artist amongst themselves. But the painted planes I remember most were the ones with the nose painted to resemble a sharks head or an eagles head etc. I imagine they were probably the squadron's insignia? I needn't look it up on google, because all the ex-air force types will tell me soon enough. Then of course I remember well the stripes that were introduced for the invasion on D-day. I know that was a necessity because of identification reasons. Memories!
