The image is a blackboard with white text written on it. The text is written in Vietnamese and appears to be an introduction to the Vietnam National Museum of History. The background of the blackboard is white and the text is in black. The title of the text reads "Loi giồi thieu | Introduction" which translates to "Introduction" in English. Below the title, there is a list of the names of the museum's visitors and their names in Vietnamese. 

The text is divided into two columns, with the first column on the left side and the second column in the middle. The first column lists the names and dates of the visitors, while the last column lists their names. The names are written in both Vietnamese and English, and the dates are listed in a smaller font size.

At the bottom of the image, there are two bullet points that explain the museum and its history. The museum's logo is also visible in the bottom right corner.
