From the back cover:
In October 1931, Dick Tracy debuted in American newspapers. Through extensive research and interviews with Chester Gould (the creator of "Dick Tracy"), his assistants, Dick Locher (the current artist), Max Allan Collins (who scripted the stories for more than 15 years) and many others, the author reveals how the detective has become a cultural icon.
Dick Tracy paraphernalia and the 1990 movie Dick Tracy are fully discussed, as are the detective's appearances in other media -- books, comics, radio, movie serials, "B" movies, television dramas, and animated cartoons.
