In 1970, Charles White had a solo exhibition at Forum Gallery, Madison Avenue, New York City. The exhibition was announced by this substantial preview card that was folded (shown here in its unfolded state). The reverse of the card was blank. The card, unfolded, measured 38 x 23.5 centimeters. The image on the card was "Wanted Poster Series #3", produced the previous year, 1969. The measurements given were 24 x 24, though it was not stated if these were inches or centimeters.
