Stencil on Market and Franklin, San Francisco 

Blek le Rat's "Stencil on Market and Franklin, San Francisco" is a striking example of street art, employing a black and white stencil technique. The work depicts a figure in a crouched position, seemingly peering through a window frame, which reinforces the sense of observation and anonymity inherent in street art. Blek le Rat, born in 1952, is a pioneer of stencil art, known for his politically charged and often poignant depictions of everyday people. This piece, like much of his work, reflects his interest in urban landscapes and social commentary.
