We have been studying the artist Charley Harper. Charley Harper was an illustrator and artist for 60 years. He developed a style he called minimal realism. His work is characterized by simple shapes, bright colors and subtle humor. There is a new retrospective book of his work coming out, put together by designer Todd Oldham, who became friends with Harper after discovering and admiring his work. I did not have any luck finding books on Harper at the library, so ordered a few resources from Amazon.
I had to make a Harper card too.
