I've added a new folder called "Original Anthropomorphic Representations", with the intention to separate them from deviations that document actual historical objects and people. So, the new folder contains pictures and drawings that represent the BeNeLux countries in a human form that are made by artists active on this site. Such drawings have been in our collection for quite some time, but they always looked rather out of place, as most submitted deviations document rather than "transform" information from the past.
So, to clarify, a Hetalia fanart of Belgium during the Spanish era would belong in the new folder, but a WWI postcard representing Belgium would still belong in the WWI folder. Same goes for Polandball or Countryball comics featuring Belgium, the Netherlands and Luxembourg balls should also be added to this folder.
Naturally, the main criterium for inclusion is the historical content of the artwork.
