The image shows a simple line drawing of a ruler. The ruler is black and white, with the numbers "0" and "1" visible on the top and bottom edges, respectively. The ruler appears to be a standard rectangular shape with a series of evenly spaced lines that represent the measurement marks. The background of the image is plain white, which contrasts with the black lines of the ruler, making it stand out. The style of the image is minimalistic and appears to be a hand-drawn sketch rather than a photograph.
