For Seattle artist Gregory L Blackstock, who is autistic, the world is made up of countless things needing to be identified, ordered, and arranged—be they turkeys or cougars, flags or fireworks. Once he chooses a subject, he seeks to record all the variations within that group, to make the artwork “complete.” This process yields intricately tiled and labeled freehand drawings that span multiple pieces of paper added with tape and glue. Since his first solo art show in 2004 at age fifty-eight, his list-like drawings have captivated art lovers worldwide.
