Summary
This is a scale model of a Tyrannosaurus rex exhibit which was planned by the American Museum of Natural History but never executed. The image was published in a 1913 paper written by Museum president Henry Fairfield Osborn, who died in 1935. Because the paper was published before 1923 and because the author (Osborn) died more than 70 years ago, it is here considered to be in the public domain.
