This is the work of the Czech artist and illustrator Mirko Hanák (1921-1951).
I am amazed everytime by the way he has perfected his skills.
This is all done way before you could manipulate things with computers, this is all done by hand.
I know how hard it is to control chance when doing watercolours. Where to let the paint spread, and when to keep it crisp (and then: how!?).
I bow deeply..
