I had another presentation to do, and this time I picked one of my all time favorite illustrators: Richard Scarry. I prefer his earlier work from the '50s and '60s, personally.
This last guy wasn't done by Scarry, but I still adore it. I couldn't find anyone to credit, so just accept it's cuteness and know it's not mine. (Though the lettering certainly looks as if I could have doodled it.)
