The Darkness Easter Egg - 1337 Reference

And i probably am the first to announce i found an easter egg in the darkness. Probably the first one to announce it to the internet too :D.

How to find it? Use the subway to go to canal.St, now take go to the corridor wich leads to chinatown, instead of going right to that corridor, go left. Here you can see some posters, one of the posters says in bold "PLANET", now look down on the same poster, there stands 1337. Give it a try :D.
