A dense grid of interlocking geometric shapes in hot pink, bright yellow, electric blue, kelly green, and black creates a kinetic rhythm across the composition. The pattern repeats with precision, evoking the optimistic energy of mid-century artwork while its layered rectangles and circles suggest movement and visual depth. 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.
