Historical context
Köhler produced this hand-colored engraving in 1887. The piece is held by Wikimedia Commons (institutional source) and is in the public domain under Public Domain; we sourced the file from the institution’s open-access program and prepared it for archival printing.
The master file is 1572 × 2168 pixels. At 300 DPI it prints clean at approximately 7 inches on the long edge before any visible loss; below that scale all three included print sizes hold cleanly.
