This information is taken from Soul in the Stone Cemetery Art From America's Heartland by John Gary Brown and was accompanied by a great photograph.
"A memorial to the Morrison brothers recalls their short lives as invalids, one confined to a wheelchair and the other to his crib. The chair's wheels are broken by design, but the meaning is not altogether clear. They may symbolize broken lives and impermanence of all earthly things. On the other hand, they could represent the child's freedom from his earthly prison of pain and illness. This striking but quickly deteriorating monument is at Calvary Cemetery in St. Louis. The impact of this image is unusually morose for an American monument.. The children's eyes seem to be full of uncomprehending terror, bringing to mind the bitter, nihilistic makers that haunt some of Europe's metropolitan cemeteries."I was so intrigued by the photograph and the description of this specific monument I had to go see it for myself. I definitely wasn't disappointed. My photos are not the best, it was over cast and rainy when I went.
