The 1850s sit at a productive crossroads in printmaking: lithography had matured enough to support mass illustration, but the work still carried the hand of individual artists rather than the anonymity of later industrial reproduction. J.J. Grandville, the French caricaturist known for his satirical animal allegories, exemplifies the era's wit and draftsmanship. Natural history illustration flourished alongside social satire, with hand-colored plates appearing in scientific journals and popular books alike. The period originals here come from that moment.
