A gridded street map of Chicago unfolds in white lines against a deep blue background, rendered in the clean, technical style of architectural blueprints. The composition captures the city's orthogonal layout and major thoroughfares with precision, creating a sense of order and urban structure while maintaining the understated elegance of vintage planning documents. 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.
