In collecting African American Art, I generally look for works that document particular movements of trends in art or that document different historical periods. This selection leads to a varied collection that includes both race and race less art. To exhibit one or two pieces does not begin to tell a story. But a story or movement begins to evolve when scores or hundreds of works are exhibited. Art, after all, is visual literature and oftentimes speaks more powerfully and with greater clarity and articulation than the best drama.
Technical ability is a given criterion.
Buy art that you like and within your means. When starting with limited funds, buy contemporary artists that are now releasing new works. You may collect tomorrow's masters. Remarques, Artist Proofs, Printers Proofs and Limited Edition pieces will appreciate in value more than open edition pieces. The market and the going prices for art are dictated by supply and demand.
