A luminous sphere radiates outward in concentric waves of electric blue, teal, yellow, orange, and magenta, dissolving into deep black at the edges. The form suggests both a celestial body and an internal explosion, painted with soft gradations that create an almost otherworldly glow against the dark ground. 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.
