I think the entries such as Chaplin/Einstein shouldn't be allowed, because let's be real, neither is attached to the 1800's, Chaplin in particular. I don't think it's being picky, both are known specifically for what they did in the 1900's, they don't belong in this contest.
I probably would also be more strict, but when the majority of submissions got disqualified that could at some point demotivate people to participate at all. We already have the jury as an additional quality control. Such borderline cases probably won't make it far, anyway.
And I continue to be annoyed with the people who can't follow the very clear and simple contest rules that have been laid out. 74 is nearly half the entries. How hard is it to follow the rules?
I wonder, if the people who took more liberties were at least more creative. Otherwise I can see no point.
Maybe some people just don't do the research. When you're young, Chaplin or Einstein might be historical figures like many others. But then again, one cannot assume that everything from the past took place exactly in the 1800's. Where there submissions of dinosaurs or the like, Janina ?
A quote attributed to Einstein just comes to my mind about the dimensions of the universe and the human intellect. There could be some truth to it.
