About the pictogram thing.... all of the symbols on there but one have been seen on the show- the glasses. Everyone thinks that they are Stan 's glasses, but if you look, the frames are not the right shape. Thus, I think that those glasses actually belong to the books ' author, who has not yet been revealed in the show.
