A classic checkerboard pattern of alternating black and white squares appears to ripple and undulate across the composition, as if the flat grid has been bent and warped by an invisible force. The optical distortion creates a hypnotic, three-dimensional effect that challenges the eye's perception of what should be rigid geometry. 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.
