"BE HAPPY" appears in bold white and pastel lettering across a red ground, accompanied by a diagonal rainbow stripe of green, yellow, and pink that sweeps toward the lower right corner. The composition combines retro typography with a graphic, optimistic aesthetic that channels the bold simplicity of mid-century poster 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.
