This is a sculpture by the Cuban sculptor Yoan Capote (2008)

Here is a maze shown that looks like a brain. It is not that huge, but it seems difficult to find the right way out of it. We can see a few men. They are walking into it, going through the labyrinth or standing in it and one person is standing in front of stairs into/ out of the maze.
The personon symbolise that there could be many 'right' ways or they are something like obstacles or stones in the way when you want to walk through the labyrinth.

A good title for this sculpture in connection with the book 'Looking for Alaska' could be 'The Labyrinth of Live'.

Personally, I would think that Alaska would like this sculpture, because it fits to what she says and it is an plausible answer to her question waht the labyrinth is.
