Are oil paintings considered valid historical imaging materials?

Does not belong.

Effective historical image materials refer to image materials that can truly reflect historical events, characters or social phenomena, such as photos, films, videos, etc. These image data can provide intuitive and vivid evidence to help people better understand historical events or social phenomena. Oil painting is a form of painting. Although it can show historical events or social phenomena through the content of the picture, it is not an image material in itself. Therefore, oil paintings cannot be regarded as valid image historical materials.
