Highly interesting blog at LICHTENSTEINPROJECT
aimed at digging up the actual comic book panels that formed the basis for Roy Lichtenstein's famous paintings...
What surprised me the most is how closely he stayed to the original images, even the speech bubble texts were sometimes copied directly...of course, when you appropriate/steal/borrow/find inspiration from trained professionals, you don't have to worry about unbalanced compositions or spelling errors!
Panzer: Sdkfz 231 (8-rad)
Speeding down a road during the Polish campaign. Note the white national crosses and tactical marking of a Panzer unit - a rhomboid.
Sdkfz 231's were still serving with armoured recon detachments when WWII ended in 1945, some of the very few vehicles in the Panzerwaffe's inventory to survive unchanged except for upgraded radio equipment.
