Over a career span of more than forty years, Alan Flattmann has become recognized as one of the most influential and respected pastel artists in the country. He is a Pastel Society of America's Hall of Fame Honoree and Eminent Pastelists of the International Association of Pastel Societies (IAPS).
Although accomplished in oil and watercolor, Flattmann is best known for his work in pastel. In 1987, ’90, ’91 and ’92, Watson Guptill published and reprinted his book The Art of Pastel Painting. Alan revised the book in 2007 (Pelican Publishing) and it is still considered by many as the definitive guide to pastels. Flattmann's work is also the subject of three additional books; An Artist's Vision of New Orleans: The Paintings of Alan Flattmann (2014, Pelican Publishing), Alan Flattmann's French Quarter Impressions (2002, Pelican Publishing) and The Poetic Realism of Alan Flattmann (1981, A.C.M. Publishing)
As well as receiving many awards and honors during the course of his career, Flattmann's work is featured in many art books and magazines such as American Artist, The Pastel Journal, Pastel Artist International, Watercolor, Southwest Art and the French magazine Pratique des Arts. His work has also been shown in over 60 solo exhibitions and included in major group exhibitions in the USA, France, Columbia, China and Taiwan. In addition, his paintings are found in the public collections of the Hang Ming Shi Pastel Art Museum (Suzhou, China), The Butler Institute of American Art, The New Orleans Museum of Art, Ogden Museum of Southern Art, Oklahoma Art Center, Longview Museum of Art, Mississippi Museum of Art, Lauren Rogers Museum of Art, Sarah Gillespie Museum (William Carey University), St. Tammany Parish Justice Center and Alton Ochsner Medical Foundation, as well as hundreds of private and corporate collections.
