I saw a documentary on PBS a couple days ago, the film was titled "Colored Frames". The doc was very informative about the plight of black american artists. Much of the information was the standard talk have heard for years.
When I see stories about artists, I am always interested in how the artists put bread on the table. Interviewers seem to skirt around the money part of an artist's life. Survival as an artist is very important. The questions about survival,sales,collectors, and day to day life should be asked.
