 ”Dennis Bille one day came around with a quite large set of folders and unpacked these wonderfull illustrations. Obviously they once were give-a-ways from “United States Steel International” to show, how the future might look like - from a early 60s perspective. Dennis Bille got these folders from a retired designer as a gift for helping to close down his office.”
