These sculptures provided a unique display that became Jim Gary's hallmark by the early 1970s and soon it became the traveling exhibition, "Jim Gary's Twentieth Century Dinosaurs", which appealed to toddlers through grandparents. Some of his signature sculptures in the exhibition exceeded sixty feet and Gary frequently painted them in bright colors using automobile paints. They were often transported to exhibitions on huge, open flatbed trucks, fascinating fellow travelers on the roads. Impromptu parades formed as drivers followed the dinosaurs to their destination or a stopping point, where people milled around the trucks asking questions and admiring the sculptures.
