LeRoy Neiman is an American artist known for his brilliantly colored, semi-abstract paintings and screen prints of athletes and sporting events...

...LeRoy Neiman is probably the most popular sports artist in the world, followed only by younger artists Stephan Holland and Richard T. Slone. Neiman produces about six different serigraph subjects a year, generally priced from $3,000 to $6,000 each. Gross annual sales of new serigraphs alone top $10 million. Original's can sell for up to $500,000 for works such as "Stretch Stampede," a mammoth 1975 oil painting of the Kentucky Derby bearing that price tag. In addition to being an internationally renowned sports artist, Neiman has created many works from his experience on safari, including a series of animal portraits that are some of his most sought-after pieces, including "Portrait of the Lion," "Portrait of the Elephant," and "Portrait of the Tiger." Some of his other subjects include sailing, cuisine, golf, boxing, horses, celebrities, famous locations, and America at play. Much of his work has been done for Playboy Magazine, for which he still illustrates monthly.

Neiman works in oil, enamel, watercolor, pencil drawings, pastels, serigraphy and some lithographs and etching. In 2007, he was presented with the Sport Artist of the Year Award from the United States Sports Academy. Neiman is listed in Art Collector's Almanac, Who's Who in the East, Who's Who in American Art, Who's Who in America, Who's Who in the World. His works have been displayed in museums, sold at auction, and displayed in galleries and major online distributors. He has begun to join the ranks of artists whose works can command prices over $100,000.

His works are distributed by Hammer Graphics (who have represented him for over 35 years) and Knoedler Publishing Co. of New York and sold by many galleries and dealers.
