Casts of horncores (just the tips) of the horned dinosaur Triceratops and tooth of a carnivorous dinosaur, possibly Tyrannosaurus or one of its close relatives.
Stereograph (number 3 of Novelview’s “Dinosaurs” series; “reverse cross” your eyes to see the picture in three dimensions) of skeleton of Triceratops mounted at the American Museum of Natural History, New York, NY. Also, a postcard depicting an encounter between Tyrannosaurus and Triceratops, one of a series of cards (“Dinosaur Postcards in Full Company,” 1985) reproducing a painting (based on a painting by Charles R. Knight) by Matthew Kalmenoff.
