This image features a simple hand-drawn sketch on an aged paper with a yellowish-brown tint. The sketch consists of a long horizontal rectangle that is divided into five smaller connected rectangles. The second rectangle from the left is heavily shaded with crisscross lines, making it stand out from the others. Beneath the sketch, there is a hand-written inscription in cursive that reads "The Minimum Unit of the 5-level Directional Coordinate is the Square". The writing appears to be in dark ink, possibly black, and there are a few ink smudges visible on the paper, one of which is directly beneath the text. The overall impression is that of a conceptual or instructional diagram.
