Poster shows a narrow alley at the end of which is a green corrugated door. On the door is the silhouette in white of two people engaged in intercourse.
In one side of the poster there's a pair of blue sandals against a pink background. Over them the caption reads "anti oursins." [anti sea urchins but meaning orphans]On the other side a drawing of a condom package in blue and a rolled condom in pink against a yellow background. The caption above it says in pink letters "anti virus."
A white wall of what seems to be a toilet stall (there's a horizontal pipe with a roll of toilet paper between it and the wall) with graffitti on it, including the poster message.
