Prickly pear cacti with pale yellow-green paddles grow thick in the foreground, their dark spines casting sharp shadows across sun-bleached soil. Behind them stretches an expansive desert plain under a soft blue sky dotted with white clouds, with distant mountains hazy along the horizon. 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.
