A smiling girl with a round face and a cheerful duck nestle among layered geometric shapes in bold primary colors, their forms dissolving into playful patterns of stripes, circles, and radiating artworks. Red, orange, blue, and cream dominate the composition in a joyful mid-century modern style that radiates warmth and childlike wonder through its confident use of flat color and organic curves. 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.
