It looks more like a zinc or copper plate etching to me. If you can show some detail of the line quality and of the corners of the print, also the writings, perhaps someone familiar with prints can help you more. What size is it?
Thanks for showing line detail, it is probably a steel plate etching, as many books were in the early 1900s. How large is it?
The number "16" is the date of the etching (1916). Rheims Cathedral was bombed during WWI in 1914. A "numbered" etching would be expressed by something like 16/100 - number 16 out of 100. Here is a 1926 article about Jacques Carlu (behinning on pg.3), including a reproduction of this particular image: https://usmodernist.org/PA/PP-1926-05.pdf The title of the etching does not appear in the view you provided us. How did you know the title?
