Issued in 1978 by the National Wildlife Federation (United States), this colorful conservation label features the distinctive Dog-Faced Sulphur butterfly (Colias cesonia) resting among wildflowers. Part of the “Our Wildlife Needs You” awareness campaign, the design highlights pollinator conservation and habitat protection themes popular in 1970s environmental initiatives. Though not a postal issue, these wildlife federation labels are widely collected as cinderella philatelic items due to their attractive artwork and conservation messaging. The vivid yellow-and-black butterfly illustration makes this piece especially desirable for topical collectors focusing on butterflies, insects, or environmental causes. Well-preserved examples remain popular additions to thematic wildlife collections.
