Charles' many watercolor images evoke memories of familiar local subjects. His natural gift for beautiful, sensitive line and color has been heightened through the private tutelage of such renowned artists as Frank E. Schoonover and Charles DeFeo. He learned his superb watercolor technique from John W. McCoy, N.A. at the Pennsylvania Academy of Fine Arts. Locally admired and collected, his watercolors are also represented in the private collections of the late John F. Kennedy, Prince Ranier of Monaco, the late Henry Fonda, and the Vatican.
