Though they duplicate the real world for fun and fantasy, models are not always toys and they’re not always tiny. We explore the magic of these fascinating replicas–from the Rover and Lander models for the Mars Exploration Project to ancient Egyptian ship models found in tombs to English ship models from the Age of Sail. We also look at the rage for hobby modeling, with Lionel trains leading the pack, watch models go to war with scale warplanes in WWII, and invade science fiction films.
