This picture has been floating round on the internet from some years now created by the excellent artist Andrea Bonazzi which supposedly depicts Arthur Machen, as one notable writer in part of a series of montages of weird authors. The only thing is it is the man in the picture is not actually Machen. The artist says he found the original photo he used for the montage on the internet clearly labelled as Arthur Machen but now the website has disappeared.
Can you identify this man? Please contact me if you can. You can see the picture in its original context on the artist’s website
