The two nondenominated Butterfly Garden Flowers stamps are intended for bulk mailings by authorized nonprofit organizations. Each stamp features one of two flowers that butterflies love to visit: scabiosas or cosmos. Inspired by block-printed textile and pattern design, the artist hand-carved the images into linoleum blocks. After inking the blocks, she pressed them onto paper, scanned the images and added color digitally. Art director Antonio Alcalá designed the stamps with original art by Rigel Stuhmiller.
