No. 15 begins with an antique plan drawn on linen in 1923, a precise piece of mill-and-dam engineering and a quiet showcase of drafting mastery. Decoupaged onto an antique drafting board, the drawing becomes both blueprint and artwork, its measured lines and hand-lettered notes as deliberate as any composition. A small vintage photo frame "houses" the title block like a caption in a vitrine, while scattered washers, nuts, salvaged appliance components, and a rusted broken car spring echo the circles, points, and notations of the draft itself, translating marks on paper into objects in space. Finished with a vintage briefcase handle, the piece becomes a portable relic that honors craft, history, and the surprising beauty of something made to be purely functional.
