I added the table to the image to give the cards some grounding, they represent the poker played by the patience when McMurphy arrived.
I placed certain carss in this image to infer elements of the story, for example I placed the queen in the hand the represent the Nurse Ratched, the ace for McMurphy and the Joker as Cheif Bromden. I also felt that the Joker should be included to show the disorganised way the patience would play, though the Joker could have been replaced with other less conforming cards, such as a hand drawn note stating "King of Hearts" or some other card of that nature.
