Cohen's paintings of the 1960s focused primarily on issues of representation: how it is that paint on a canvas can trigger different kinds of responses and associations in the viewer.
Paintings such as this are not representational in a traditional sense, in that they do not show immediately recognisable objects. But they are concerned with the mechanisms and processes of communication with the viewer. The shape that is repeated in Tribune is generalised so that viewers can interpret it as suggesting a number of different things. The bright colours also evoke sensations or suggest images from the natural world.
