On October 21, 1977, the Postal Service issued a 13-cent Christmas stamp (Scott 1730) depicting a rural mailbox. The stamp was designed by Dolli Tingle.
The multicolored 13-cent issue was printed on the Bureau of Engraving and Printing seven-color Andreotti gravure press (601) as sheets of four hundred subjects, tagged, perforated 11, and distributed as panes of one hundred (ten across and ten down). Mr. Zip, “MAIL EARLY IN THE DAY,” electric eye markings, and five plate numbers, one in each color used to print the sheet, are printed in the selvage.
