The image is a photograph of an open notebook with a graph on the pages. The graph appears to be a line graph with three peaks, each representing a different time period. The peaks are arranged in a vertical line, with the highest peak at the top and the lowest at the bottom. The lines are drawn in a simple, hand-drawn style.

On the top left corner of the notebook, there is a note written in French that reads "Aurore 8 ans 14/11/20" which translates to "Marcel pour le refuge, il mous pleut bancoupe" in English. Below the note, there are two lines, one representing the time period and the other representing the frequency of the waveform. The note is written in a cursive font and is signed by a person's signature in the bottom right corner. The notebook is resting on a green and white patterned tablecloth.
