Description
This pictorial statistic conveys that most patients get less that 10 injections of treatment and that only a few injections commonly leads to relapses of syphilis. It uses images of syringes and men sitting and standing to represent the statistics. It is a graphic print for an image that appeared in Parran's 1937 book, Shadow on the Land.
