2019 USPS California Dogface Butterfly Non-Machineable Stamps 100Pcs/Pack

California Dogface graces the seventh non-machineable butterfly stamp for use on irregularly sized envelopes, such as square greeting cards, invitations or announcements. The stamp art was digitally created using images of preserved butterflies as a starting point. The result is a highly stylized, simplified image of a California dogface (Zerene eurydice) rather than an exact replica. Nationally known artist Tom Engeman created the stamp art. Art director Derry Noyes designed the stamp.
