Announced November 1, 2021:

These four new stamps celebrate the beauty of mountain flowers. Each Mountain Flora stamp features a different flower: a purple pasqueflower, an orange-red wood lily, a bright yellow alpine buttercup and a dark pink Woods’ rose. The artist’s hand-drawn illustrations, refined digitally, create a block-print aesthetic. The stamps will be issued in booklets of 20 and coils of 3,000 and 10,000. Art director Ethel Kessler designed the stamps with original art by Lili Arnold.

Additional information will be posted below the line, with the newest at the top.
