Earlier this year, Belgian film-maker and artist Vincent Bal stumbled upon an uncanny resemblance to an elephant in the shadow of his tea cup. This gave him the idea for Shadowology, a series of doodles that interact with the shadows of simple, everyday objects: a banknote, some ice cubes and a flower, for example, can turn into a church, a woman and a hippy. “I draw a few lines and I get my image. It’s really the shadows that inspire me”, Bal says. Here: “Stonedog”. (Photo by Vincent Bal/The Guardian)

Sébastien Del Grosso is a French artist and a photographer, who will allow you to enter the world of surrealism, which combines photography and hand-drawn art. His works masterfully blur the transition between the real photo and the picture. By viewing his works, we can see that Sébastien is not only a master of creating photo illusions, but also a person who tries to show his inner world through his art. His emotions, his feelings, his fears and desires are all vividly and skillfully expressed in simple strokes of a pencil. He is the continuation of his art. So much so, that he loses his identity, fearing it, but being unable to stop. (Photo by Sébastien Del Grosso)

A lithographic sketch, purportedly by Beatles star John Lennon, shows his wife Yoko Ono in a sexual context within a document released by The National Archives March 23, 2004 in London. The document, which has been classified since 1970, contains sketches and letters which were seized by police to form part of the evidence for the indecency trial against the London Art Gallery which had been displaying the material.
