Here is an original watercolor painting of a P-51 Mustang Mark 1 alongside a British Army Aeroplane No 1 (also known as the Cody 1). Painted in 1941 by Eugene Clay, a member of the P-51 design team famous for his "exploded views" of the Mustang and the redesign of the P-51 fuselage to the bubble canopy configuration of the P-51D. Very rare, and in excellent condition. If you have any questions, please feel free to write.
