Bloody hell that took a while! I started searching "Hildebrandt" as seen in the bottom corner and found out he is a fatansy artist...looked for painting etc. and managed to find the same one with the title.
Ah. Just got No.7 - its a lot easier than No. 5, which took bloody ages - especially if you haven't read the books or seen the films! (Not too much of a clue there I hope?)
