Vertical columns of concentric circles and wavy lines create a rhythmic, undulating pattern in cobalt blue against a crisp white ground. The composition evokes mid-century modern artwork sensibilities, with its geometric precision and optical movement suggesting both bubbles rising and textile weaving. 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.
