research your photograph of José Guadalupe Posada attached to that article. I am quite certain this is a photograph of José Clemente Orozco
My students are using this image as his, but a close comparison of photos makes this unlikely and I think it is misleading. What is your source attribution for this photo? Posada died in 1913 when camera technology was still limited. The sharper image of Orozco looks more like photos from the 1930's, the hair style and nose match Orozco. Images of Posada consistently have him with a longer handlebar mustache and more prominent cheekbones and never glasses. I do not believe any photos of Posada exist. This needs to be fixed.
Thank you for the notice! You are absolutely right, it was a portrait of Orozco. We've replaced it with authentic photo of Posada from a reliable source
If you or your students find any further inaccuracies or Posada's works that are not on Wikiart - please share, we'll be most grateful!
