A worn library card from the 1960s bears the title "The Wonderful World of Music" and displays a creased, yellowed surface marked by dozens of stamped checkout dates and handwritten borrower names in fading ink. The composition captures the tactile history of repeated use, with overlapping date stamps in red and purple creating a dense, layered pattern that tells the story of countless readers who held this same card. 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.
