Discover ‘Cognoscenti in a Room hung with Pictures’ as a beautiful National Gallery 1000 Piece Jigsaw Puzzle. Painted in 1620, this image by Flemish features eleven finely dressed men who are inspecting artwork in a large room. The paintings are thought to be miniature copies of real art by artists from the 16th and 17th centuries, and the collection of them in one room is thought to be a fantasy that Flemish had.
