The late John Rayson also produced brilliant caricatures of RAF "types", ranging from oil-stained knuckle-scraping "Chiefies" to wet-behind-the-ears sprog Pilot Officers etc. I know this is getting away from aviation art, (possibly!) but they are very good!
I also recall seeing a fantastic Rayson Lightning thundering out of Binbrook in murky Lincs weather - you can feel the ground shaking!
