This Article shows how to solve the four slots wall puzzle (Lithograph Stone Puzzle) to reach the Bindery to get the Red Ink
As you go through Chapter 5 to locate the ingredients, you will likely encounter a wall featuring two lithograph sets attached to it and two empty slots.
So, your first task is to locate these two missing stone tablets. Luckily both are located nearby. One of these tablets can be easily located within the very same room on a sofa as the lithograph puzzle.
While the other rests on a desk in a room further down the main hallway on a table in front of the merchant. Refer to the map above.
After acquiring both lithographs, come back to the puzzle and insert the tablets into the vacant slots. Observe that beside each slot is a symbol, with two of them partially faded. These symbols correspond to the symbols on the lithographs. To solve this puzzle, you must not only match the correct symbol but also choose and flip the colors of the lithographs appropriately.
