This picture, or at least the look, was inspired by the work of London artist Clark McDougall who died of a brain tumour at the age of 59 back in December of 1980.
McDougall did a number of paintings in which objects in the scene were outlined in black paint. A painting from this period in McDougall's career hung on the wall at The London Free Press when I worked there.
This is a birch tree just off Wharncliffe Road on the way to Lambeth. It was dusk and the tree had a wonderful warm glow which looked all the warmer juxtaposed against the cool, blue sky.
