René Magritte advertising

Before making a name for himself as a surrealist painter the Belgian artist René Magritte made ends meet by creating advertising artwork.

Not just any old artwork mind you.

This is beautiful art deco art.

I imagine original posters of these ads would fetch quite a bit of money these days.

But I wonder if people who bought them would know they were created by one of the great art figures of the 20th century?
