Mercedes Seagull wings - airbrush on cardboard

Mercedes Seagull airbrush

One of my old paintings and illustrations of old cars, American cars and hod rods made in the 1990s.
Any technique would do: pencil, pastels, oil or acrylic on canvas, but my favorite technique, which was perfect for the shiny American cars of the 1950s, was the airbrush, which I learned to use as a self-taught artist.
