Dozens of meticulously detailed insects and birds fill this naturalistic chart in warm earth tones, ochres, and forest greens against a cream background. Each specimen is rendered with scientific precision in what appears to be a vintage natural history illustration, arranged in dense rows that celebrate the extraordinary diversity of the insect world. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
