The image is a photograph of a plaque on a stone wall. The plaque is rectangular in shape and has Chinese characters written on it in both English and Chinese. The text on the plaque reads "Exhibition of Cultural History of Shanghai Prehistoric Age" and "Preface". Below the text, there is a brief description of the exhibition, which explains that during the prehistory era, Shanghai was the most developed region in China. The exhibition was established in the early 20th century and was held in Shanghai, China.

The plaque appears to be old and weathered, with some cracks and chips in the stone. The background of the image is dark, making the text stand out.
