This is one of the numbers papers with the rare backwards "33" as seen throughout the film. The letter is chelaced to protect it from the rain and water. The "33" was used forwards and backwards leading to the early idea in the film that perhaps Lucinda was "dislexic". However, later in the film, the backwards "33" becomes more "square", leading to the idea that the numbers are actually letters, and stand for "everyone else". This is the "middle version" of that conversion. All 3 types can be seen throughout the film. I have only seen one other letter with the backwards 33 and that letter was sealed inside the screen-used capsule. Would love to know what happened to the others!
