i couldn't find it in the GSD forum, but there is another post in the bonfire here.
i can't figure out the answer either. i thought after the clues:
- USPA pg 78 "Carving is easy, you just go down to the skin and stop"
- Website source "Michelangelo painted his self portrait on the alter wall of the sistine chapel.
...can you find it"
That it would either be:
- Last Judgement
- Blue Skies
i'm done wasting my morning on it.
