Smiling cartoon faces in bright yellow, blue, red, green, and purple fill a black background in a dense, repeating pattern that recalls 1970s pop art and vintage character artwork. Each rounded face beams with cheerful expression, their simple closed eyes and wide grins creating an infectiously playful mood across the composition. 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.
