A cream-colored echidna faces forward with its distinctive spiky quills fanned upward in shades of golden brown and tan, against a soft sage green background. The illustration employs a geometric, modernist approach with clean lines and flat color fields, capturing the animal's round body and alert expression with minimal but expressive detail. 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.
