About This Stamp
The 13-cent Energy Conservation/Development special issue stamps were first available on October 20, 1977, at Washington, D.C. The design of the two stamps is identical except for the titles: Energy Conservation and Energy Development. The se-tenant (vertically) pair depicts a house, a gasoline container, and a light bulb. They were designed by Terrance McCaffrey.
The multicolored 13-cent issue was printed on the Bureau of Engraving and Printing seven-color Andreotti gravure press (601) as sheets of 160 subjects, tagged, perforated 11, and distributed as panes of 40 (five across and eight down). Mr. Zip, “MAIL EARLY IN THE DAY,” electric eye markings, and six plate numbers, one in each color used to print the sheet, are printed in the selvage.
