I'm doing some research on visual artists and their career trajectories and would love artists' opinions. I would like to know the different paths artists have taken from art school in order to get a dealer and how their careers have progressed. I am also interested in what artists think are the main points in time at which their career progresses (e.g. getting a dealer, getting into a major collection/museum, etc)? Thanks a lot for any help!
