About This Stamp
The Post Office Department drew attention to the importance of wildlife conservation with a series of three commemorative stamps issued in 1956. The stamps featured images of the wild turkey, the Pronghorn antelope, and the King Salmon. Each of the Wildlife Conservation stamps paid the postage on a one-ounce first-class domestic letter.
Each of the three intaglio stamps, perforated 11x10 1/2, was printed on the Stickney rotary press from 200-subject plates. Printers used the plates in pairs on the press, so each rotation of the press produced two sheets of 200 stamps, each of which was divided into four 50-subject panes for distribution to post offices.
The third and final stamp in the series, the 3-cent King Salmon, was issued on November 9, 1956, in Seattle, Washington, at a ceremony co-sponsored by the Salmon Industry of the Northwest and the Seattle Chamber of Commerce. As with the other stamps in the series, Robert W. Hines designed the vignette and Victor S. McCloskey designed the frame. The engravers of the die were Matthew D. Fenton (vignette) and John S. Edmondson. The four plates used to print the stamp were 25496, 25497, 25498, and 25499.
