you could keep that award but printing the book for some patreons (those who contribute the most). Obviously it is more money (not only the printing if not the design and the transfer) but someone who puts a considerable amount of money surely wants the book in physical (it is just an idea).
I did not know that the original art was prohibited, surely the person who shared it either considering that he is quite a fan of the game and always supports you in his comments (I do not know the guy, I only say what I read)
