Undulating vertical stripes in chartreuse yellow and periwinkle blue create a mesmerizing wave pattern that seems to ripple across the composition. The rhythmic, symmetrical artwork evokes the aesthetic of 1970s graphic art, with its bold color blocking and hypnotic optical effect. 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.
