"Gratitude" is a the name of an inspirational photograph taken in the 1960s by Jack Garren, a religious bookstore owner from Centralia, Illinois. It features an elderly woman seated at a table praying over a bible; a pitcher and plate of cheese and bread are in the background. The photograph was intended to match a 1918 photograph of an old man praying at a table called Grace by Eric Enstrom, and subsequently they have often been packaged together as a "Grace and Gratitude" diptych.
