A golf driver patent from 1924 unfolds across a classic blueprint grid in crisp white line drawings against a deep cobalt ground. Multiple technical views show the club head from different angles with precise measurements and annotations, capturing the mechanical precision of early golf equipment artwork with the formal rigor of an engineering diagram. Printed to order on a soft, absorbent mat with a no-slip backing, ready underfoot the moment you step out. The kind of art you don't expect on a bathroom floor.
