Story about a painter who saw the boy in the casket under the REAL painting.?

So, there is a story about this painter, who saw another artist%26#039;s work, and there was nothing wrong with the painting, but the artist insisted it was gloomy and weird, but no one believed him, and he went crazy or something, then, they found out that under the real painting, the original artist had used an old canvas, and in the center of the painting, under the real painting was the casket of a little boy.





I want to know what the name of the painting was, who the artist was that saw the casket and who orginally painted the picture, and where I can find more entertaining stories like this one.








It is really driving me insane, and I cant find it anywhere. :/.





PLEASE say you can help?!?
