Nested rectangular rings in black, olive green, and beige create a rhythmic optical pattern that appears to fold and recede into space. The concentric forms radiate outward with mathematical precision, their clean lines and flat color blocks evoking mid-century modernist abstraction and graphic artwork sensibilities. 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.
