Ballerina II by Joan Miro – 1000 Piece Jigsaw Puzzle (Eurographics)

A wall of deep blue, worn back to gold at the edges, and almost nothing on it: a red heart, a black and white moon hanging on a thread, one long thin arm curving up out of the dark. Miró has signed it down in the bottom corner.

Trails of tiny yellow-green dots loop away down the left with a few red ones among them. The heart is the only warm thing in the whole picture, and it holds the lot together.
