Two great crested grebes float on rippling blue water, their distinctive black and orange plumage rendered with naturalistic precision against a soft, cloud-filled sky. The composition captures the birds in graceful profile, their elongated necks and intricate feather detail suggesting a scientific illustration from a Victorian-era ornithological study. 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.
