We didn't take photos at the Old National Museum, but I found these 2 images of the Peter Cornelius exhibit on the internet and scanned the 3rd from a museum brochure I kept. They do not do the drawings justice. The subject was the Greek Gods and had scenes from the Battle of Troy, Hercules' life, and feats of Eros. Keep in mind that these drawings were HUGE, measuring in meters, not inches.
