A busy person’s correspondence card was perfect for those in a hurry and others who just didn’t know what to write on the back of a postcard. By marking the little boxes, similar to filling out a survey, a message is created when read from start to finish. Some may mark the boxes in such a way that the end result is funny. Most of these postcards also include an image. This postcard features the Wrigley Building and the Chicago Tribune Tower on Michigan Avenue. Maybe one day email services will offer a similar option to help those who don't like to write. This postcard is from the "linen era" from 1930 to 1945. While the colors in the images are brighter due to the high rag content in them, experts say the images are not as clear as they are in postcards from previous decades, and cheap dyes often make the quality of the images worse. This postcard was published by Cameo Greeting Card Co. of Chicago.
