A dense catalog of reptiles and amphibians fills this hand-colored engraving, arranged in three horizontal registers from snakes and lizards at top to crocodilians in the middle and turtles below. Ochre, sage green, and cream tones dominate the naturalistic palette, rendered with fine cross-hatching and delicate linework characteristic 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.
