It is titled "GRACE". It was originally a photograph by Eric Enstrom, shot at his photography studio in the tiny mining town of Bovey, Minnesota, back in the year of 1918.
Enstrom took this picture to show people that even though they had to do without many things because of the war they still had much to be thankful for.
The early pictures were printed either in black and white, or in sepia (brown tone). Later, Mrs. Rhoda Nyberg (Enstrom's daughter), of Coleraine, Minnesota, brought the photo to life, hand-painting them in oils, and interest in the picture mounted, and widespread distribution with her colorization. She died at the age of 95 on February 21, 2012.
