Three technical drawings of a Boeing 777 airliner appear in white linework against a charcoal chalkboard ground, showing the aircraft from side profile, top-down, and front views. The patent-style composition uses precise engineering illustration to capture the plane's sleek fuselage, extended wings, and landing gear configuration with clinical clarity and minimal ornamentation. 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.
