English Alphabet Letter Shapes

Brief

For this contest I would like you to select a letter from the English alphabet and take a photo of an object which clearly shows the shape of that letter. Avoid letters on signs or in books, newspapers and magazines, but think creatively about shapes in nature and man-made objects. For example a branch of a tree may become a "y", a rope laid on the ground may become an ‘s’, and leaded lights in a window may become an "x".
