Interlocking pink and blue geometric shapes dance across a beige ground, creating a rhythmic composition that suggests sound waves or musical vibrations in motion. The bold, flat color fields and playful arrangement of curved arcs, circles, and angular forms evoke the optimistic energy of mid-century modernism with a contemporary, funky edge. 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.
