This comprehensive series of stamps, issued in 1982, was a celebration of the unique natural heritage of each of the 50 states. The Washington stamp is a lovely composition that brings together two of the state's most beloved natural symbols. The Willow Goldfinch, the state bird, is a cheerful and common sight in Washington's gardens and woodlands. The Coast Rhododendron, the state flower, is a beautiful native shrub that bursts into spectacular bloom in the spring. This stamp is a tribute to the rich biodiversity of Washington and a reminder of the importance of preserving the state's natural beauty.
