Sidney E. King (August 22, 1906 - April 24, 2002) was an artist known for his paintings and murals for the National Park Service. Born in Dorchester, Massachusetts, he studied under John Singer Sargent in nearby Boston. He is believed to have painted the largest mural ever in the United States, a 400 foot by 75 foot high painting "Creation" along a dome in Salt Lake City, Utah. His paintings told a young Queen Elizabeth II the story of Jamestown during her 1957 visit. He continued painting six days a week until the age of 92.
A mirror-image portion of his painting Capture of Ricketts' Battery, depicting action during the First Battle of Bull Run, was used as the cover artwork for the game Glory Road, and a portion of this painting was also used for at least one of the cards for the game The War Between the States.
