Cheerful green and blue planets with smiling faces float across a light blue checkered background in a playful, symmetrical grid. The retro cartoon style brings a nostalgic 1970s energy with its simple shapes, bold outlines, and optimistic character artwork. 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.
