Dinosaur/Paleontology Expo Guidebooks

Dinosaur/Paleontology Expo Guidebooks
At dinosaur expos, the image of dinosaurs/paleontology of the time is depicted. Comparing guidebooks from 1970s dinosaur expos with recent ones, you'll be surprised at the differences in the reconstructed figures.
Tyrannosaurus started having feathers, dinosaurs are now more often compared to birds than lizards... These guidebooks allow us to enjoy these changes. As research progresses, the depicted figures will continue to change, so I want to preserve current guidebooks to look back and feel "how much things have changed."
