Libby's was founded in Chicago in the late 1800s. The business began by selling a canned meat product in a trapezoid shaped tin container. Around the turn of the century, the company started selling canned fruits and vegetables, as well. Although Libby's still includes canned meats in their line of products, they are known for their large selection of fruit juices, condiments, and both frozen and canned fruits and vegetables.
In the 1950s and 1960s, special sales on Libby's canned vegetables were marketed as Green Thumb Sales. This button is likely related to a special sale during this time period.
