Interlocking arches and vertical lines compose a rhythmic geometric pattern in black and white, creating an optical illusion of depth and movement across the composition. The repeating motif suggests both architectural forms and abstract waves, with precise linework that shifts between curved and straight elements to build visual harmony. 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.
