[3] Sweezy's mother died early, so he lived full-time at the Mennonite Mission School at Darlington Agency.
Although he never received formal art training, he loved drawing and painting from an early age.
[5] Sweezy worked in watercolors on paper and oil on canvas,[6] as well as house paint on board.
[2] Sweezy developed a technique, employed by later Southern Plains artists, of painting an active Native American Church meeting by rolling up the tipi flaps to reveal the participants inside.
If I had to miss that, I have had the next best thing: I have seen old warriors wearing their fine trappings, and I have heard them tell their stories... –Carl Sweezy, 1950[6]
