The illustration is the famous 1590 Dutch engraving based on a drawing by British explorer John White. Shows a native of Virginia with a longbow. The bow has always been thought to seem more like an English longbow - still around at that time - with its rounded limbs and full handle-to-tip taper. I did a sort of repro, using Ipe (Brazilian) laminated with bamboo., made more like an eastern Woodland bow. Flat and even width out until about a foot from tips Mine, 71" long, draws 70 pounds at 27". My son modeling and mugging
