Outsider art is saluted at columbia, then lost anew (summary)

Sam Steinberg was a foreign street seller that used to go to Columbia University to meet students and sell his paintings. He would always be enthusiastic about his works, saying: “Hey boys, I got paintings here!”, but rare was the student that bought something from him. When he passed at 85, most of his art ended up in the trash. He was not in museums, nor was he considered a great artist, but rather seen as a joke. When the students graduated, they left Sam's paintings as well, except for one person; Randy Nichols. When he planned his class' 40th reunion, he brought 90 of Sam's best works and displayed them for everyone. Many people came to see them, but they were packed in black bags and got mistaken as trash, so one more time, Sam Steinberg's art got a painful destination.
