Hidden Nuggets we see all the time...

[Iavas87]

I've decided to add a couple that I've found recently:

The following letter is located in the library of the Great Smials of Tuckborough. I'm having some trouble making out what it says, so I can only hope that it is another great easter egg.



Also, the Cirth runes above Dwalin's throne in Thorin's Hall say "Thraainul", which I interpret to mean "son of Thrain" - aka Thorin Oakenshield.



PS: If somebody could tell me how to embed images into my post, I'd really appreciate it.
EDIT: Done. Thanks, TheScyphozoa!
