Nightmares made vivid—the sailors eyes are wide and horrified, the images of the roach and the bedbug huge and menacing in this drawing by Harold Price. Price was a merchant seaman and illustrator who created powerful graphic images for the Education Department of the NMU, including this one from the booklet “Know the Score,” written by union founder and president Joseph Curran.
