This picture, or its title at the very least, was brought into pop-consciousness in 1976.How?
ANSWER
This Picture is titled Rene and Georgette Magritte with their dog after the war. The 1976 Single by Paul Simon takes its name from the picture and purports that Rene Magritte was a secret admirer of doo-wop music. Uncracked again.

I am so grateful to you for posting this picture because it is one of my very, very favorite songs and I want to make a little framed tribute to it to hang on mt wall.
The song by Paul Simon was released in 1984 (on ‘Hearts and Bones’). The line was altered from the title of a photo, “Rene and Georgette Magritte with their dog BEFORE the war.”
