A small yellow and red warbler perches among delicate white blossoms and slender green foliage in this hand-colored ornithological study. The composition balances botanical detail with naturalistic observation, rendered in soft greens, creams, and warm accents against a pale background in the manner of 19th-century scientific illustration. 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.
