I love Charley Harper and one of my finds of all finds was this book at the famous Strand Books. I'll let the images speak for themselves. It was such great price that I picked up one for my friend Kelly who sent me a Charley Harper holiday card last year. I love how he told Todd Oldham that when drawing birds he didn't count feathers, he counted wings when asked about his minimalist style.
I also found two juice glasses with his designs on them at Fishes Eddy which was a fun store to browse around in.
