This is no mere poster! It is a LEGITIMATE DOCUMENT salvaged from The Renaissance.
Thousands of research hours, documents, breakthroughs... all irrevocably lost in the chaos that tore the foundations of the world apart. This is one of the precious few items to have survived this long. It belonged to a great scientific mind of the period, whose work advanced his field of study by a very significant margin — a true VANGUARD of the empirical and the technological.
You are lucky to be able to display "Study of the ideal troll figure" on your walls. A great shame it is so torn; you really wish you could see what the complete picture looked like.
