In the fourth week of 1727 the habitual readers of the Bills of Mortality noticed something different in the most recent bill. The bill printed on Thursday January 9th showcased a border of skulls and crossed-bones framing the death counts in both the verso and the recto.1 The artwork of the skull was fairly simple: a bike-seat-like cranium slightly bent to the right, with triangular nostrils, three ovals as eyes and mouth, and two crossed-bones at the bottom.
