Keep in mind that this will not contribute to the "Art Appreciation" trophy if you are playing on any other difficulty level other than "One Percenter" (unlocked after a successful playthrough of any other difficulty).
NOTE: There is a glitch in the trailor park portion of Pretty Boy's chapter (second to last chapter of the game). After clearing this part in the game, you should have 88 out of 104 playing cards. If you get the 3 playing cards in this portion of the game, it will on register 2 of them but all 3 will be gone if you decide to go back and redo this area...permanently making you one card short of the entire deck. To work around this, create a backup save right before playing through this area the first time and collect only 2 out of 3 of the cards. Once you're returned to Dead End after the end of that chapter, go back to the trailer park mission (represented by a flamigo head which should say 73% complete) and collect the final card. At the very end of the mission, after you've killed the guy on the turrent, make sure your card count is at 88, and then go back to Dead End once the next mission of that chapter starts.
