Three technical drawings of a fire truck appear in white linework against a charcoal black ground, dated September 28, 1939, showing side profile, top-down, and isometric perspectives with patent notation and inventor's signature. The composition captures the mechanical precision of vintage industrial artwork, rendered in the stark contrast and technical clarity characteristic of early 20th-century patent illustrations. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
