Well first off only one is semi-anonymous(filip), but how can you call Anto Gvozdenovic anonymous? He was a very important montenegrin in history and should always be remembered. 

I agree that Njegos or King Nikola would be more appropriate, but that would give license to serbs to shut the whole thing down, and start saying njegos was serb not montenegrin, and King Nikola, although he never once said he was serb, they'd do the same thing

This picture right now is appropriate for ethnic montes because there is no conflict with the serbs over it, until you can get pass the above it will have to do.
