This is an aircraft art print.
This stunning rendition of a Macchi M.67 -- a purpose-built seaplane racer designed for the 1929 Schneider Trophy competition -- is one of Koike's classic works; the gorgeous red airframe against a foamy green sea makes for a beautiful contrast, while the power and speed conveyed by the rising spray give the work a sense of motion one cannot get from a a typical sky background.
This print is reproduced on heavy art board just like the original, and sized identical to the original, measuring 400mm x 315mm (15.75 x 12.4 inches). It's offset printed, and the color reproduction has been approved by Koike himself. The art board measures 625mm x 453mm (24.6 x 17.83), giving you the freedom to have it framed as you would like. Each print is packed in a special sleeve inside a sturdy cardboard shipping box designed especially to prevent bending during shipping
