Interact with the stand to find the paper, which contains clues or information relevant to your quest. You can click on the paper to zoom in and read it more clearly. Be sure to take note of any important details that may help you progress in the game.
it is on the table in the dining room.
There is an invisible message, to see it you have to get the lemon juice spill it over and you will get to see it.
There is secret writing (lemon juice) on the paper, and the hint from CJ says to use the light. Place the paper on the desk below the desk lamp.
