Long description

This image shows an illustration consisting of a white background on which are four black vertical lines of varying widths. The two broadest lines are on either side of the image and extend all the way from the top to the bottom of the illustration. The third line is narrower and is positioned in the centre of the image; it extends to about two thirds of the way down. The fourth line is the narrowest, and is positioned to the right of the third one; it ends about half way down the image. Just behind the broad vertical line on the left-hand side, and positioned fairly close to the bottom, is a red triangle.
