It is a photographic portrayal of a painting by René Magritte.

“When photographs are trustworthy, it is not because those photos are equivalents of real-world scenes — photographs can never be that — but because those photos are reliable records of real-world scenes.” (Source)

Fortunately, thanks to their photographic literacy, most viewers are aware of the effects of those limitations.
