Today I woke up to the sad news that Robin Williams had passed away. I was lucky enough to meet him a few times and he was always kind and obliging with autographs and photos for fans.

So, instead of posting one of my drawings today, I’ve decided to post one of his. Here’s Robin Williams’ sketch of Einstein’s Theory of Relatives, a quick doodle for a collection of celebrity drawings I compiled for a book for Koru Care, a children’s charity in New Zealand.
