A cream-colored chart displays fifteen meticulously rendered fishing flies arranged in three rows, each featuring delicate wings, hooks, and thread details in warm earth tones, rust red, and black. The composition is topped by three larger specimen flies with fuller, more ornate hackle, establishing a taxonomy-like presentation that balances scientific precision with the soft, hand-drawn quality of vintage natural history 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.
