In photos, drawings and words, Sign Language pays homage to the lost art of urban outdoor sign painting. In a working environment both novel and ambitious, author John S. Paul found success, noting, "No other job gave me such a direct impact on the urban landscape, or such physical engagement. Painting signs over Broadway in 1984 was a rare look down from the elevated height of a heroic messenger." Few books have ever provided such an insider perspective into this unique livelihood of days past. In 40 photos and 30 poems and stories, the author creates an immersion into a rarefied world on danger and beauty, raising the sense of the importance of moments and blurring the boundary between public and private space.
