New concept art about something... strange
The facebook page published an Image from directors assistants Timothy Visentin's Instagram, that apparently has been taken down afterward.
It shows: a blue print of the sewage, probably given to Bill by his father, and another image that shows... something strage. Apparently it's a tunnel with egyptians simbols.
I have two theories: it could be a 'stretched' corridor in Neibolt street house, or it's a special part of the sewage, near It's nest... where, in the book, things become surreal. This corridor could show a bit of It's story, in replacement of the vision that Richie and Mike had in the book.
