A girl with chin-length hot pink hair and oversized mirrored sunglasses reflecting geometric mountain peaks stares directly forward against a bright mint green background. She wears a white and blue baseball tee printed with "Lost in Nature," rendered in a playful, candy-colored illustration style with bold outlines and a pop-art sensibility. 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.
