A close-up photograph of a vintage aircraft turbine engine reveals concentric metal blades radiating from a central sphere, their geometric precision creating a hypnotic radial pattern. The black and white tones emphasize the mechanical symmetry and industrial craftsmanship of mid-century aviation engineering. 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.
