Koeln style pages

Oh boy. I have been trying to get dates for a large number of image files, but I think I need to very quickly get what I have online as there are a handful of images that are stubbornly not at all easy to pop into my current folders as the dates simply to not match the style in the art. So I’m going to have to bookmark a whole lot of sites to come back to so I can do this fast start to my pages so that I can then explain my rationale for dates.
