Three iconic Pittsburgh bridges are sketched in minimalist line art across warm cream and golden yellow panels, each rendered from a distinct architectural perspective. The delicate pen strokes capture the structural grace of these engineering landmarks with quiet precision, their geometric forms grounded against softly tinted backgrounds. 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.
