The CIA invert is a one-dollar value postage stamp error issued by the United States Postal Service. It is one stamp from the Americana series that were produced between 1975 and 1981. The $1 colonial rushlight holder stamp was first issued on July 2, 1979, and one pane of 100 stamps was issued with the dark brown inverted. The lamp candle holder, candle outline and text are inverted relative to the flame. About 95 copies have been accounted for. The stamp's Scott catalogue number is 1610c. This was the first United States stamp issued with a major design element printed upside down since the Dag Hammarskjöld invert error of 1962. As these $1 stamps were printed in sheets of 400, three additional panes of 100 stamps certainly existed at one time, but no trace of these has been discovered.

The Americana series was a series of United States definitive postage stamps issued between 1975 and 1981. Denominations ranged from one cent to five dollars. It superseded the Prominent Americans series, and was in turn superseded by the Great Americans series and the Transportation coils. The series consisted of twenty stamps issued in sheets, twelve issued in coils, and one produced especially for a booklet.
