Two interlocking geometric polyhedrons rendered in outline form, with the upper shape in light sage green and the lower in darker olive, share an overlapping plane in the composition. A small bright yellow triangle punctuates the lower right, adding a pop of accent color to the otherwise muted, neutral palette and creating visual tension within the clean, minimalist line-work against a soft beige ground. 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.
