This unique postcard shows an image of the Sears Tower before it was built. The image of the Sears Tower appears to be computer and/or artistically generated, and the building does not have its iconic flashing twin antennas. The Sears tower was built in 1973 and was the world’s tallest building for over a decade. The official name of the tower today is Willis Tower. This happens to be one of my favorite postcards. The back of this postcard indicates that it was released by Aero Distributing Co., Evanston, and was published by Curteichcolor 3 -D Natural Color Reproduction. The postcard also reads that the tower will be 110 stories tall and house 8,000 tenants with 7,000 Sears employees.
