Isolation

This piece, titled "A Pair of Shoes" by Van Gogh is a great example of focus point being delivered as a result of isolation.  The feeling that results from Van Gogh choosing to make an old, weathered pair of work boots the focal point is that of exhaustian.  The browns in the background could either be that of the fields from which those boots are used, or the dirt floor of the workers quarters.  The sad, defeated sole on the left looks frail in comparison to it's mate.  All this is inferred from these being the focal point, where as if they were simply an element of the piece, it would have needed many more elements to deliver the same message.
