The picture of 1988 Student Body Treasurer is supposed to be Littlefinger
The timeframe would fit age wise if they keep him the same age as in the novels, and it does bring to mind his status as Master of Coin. Cersei is the school principal
Joffrey "Lannister" is said to be the principal's son. Robert is nowhere to be seen (and his name wouldn't be Lannister anyway) and Jaime is just the school's security guard. However, we can see a blonde woman in the background when Littlefinger meets the school council and talks to Varys, Tywin and Jaime. In this universe, Cersei just divorced Robert and raised Joff under her family name (which is the only one she has respect for in the original canon anyway).- So who's that beside her in that shot? Lancel? Gregor Clegane?
- Given that he is part of the council and seems to have something that might or might not be a beard, he's possibly Pycelle.
