Quantity: 40,270,000 Printed By: Bureau of Engraving and Printing Printing Method: Giori Press Perforations: 11 Color: Black, brown and yellow U.S. #1204 was a "Special Issue," ordered by Postmaster General J. Edward Day in response to an error on U.S. #1203. After a color invert on the yellow background was found on the 1962 Dag Hammarskjold stamp, Day ordered a reprinting of the stamp - with the error. A printing of 40 million stamps was made so that the error would not be regarded as a valuable rarity. The special printing was called "Day's Folly."
