Not ready to swim with the sharks? Dive into #SharkWeek with this etching instead.? William H. Dougal engraved this copper printing plate featuring three species of shark in 1849. The illustrations were to be published in a scientific text, Ichthyology by Louis Agassiz. Dougal engraved 26 plates for this work ... which was never printed. That bites!
