Sir Reginald's Suit of Armour
Sir Reginald's Suit of Armour is a Mural in the Rise of the Tomb Raider: 20 Year Celebration DLC Blood Ties. It belongs to the Suits of Armour set and consists of a headless suit of armour. It is located in the Library.
Note the error in the description where there is a superfluous "didn't" between "I" and "put".
Easter Egg
Sir Reginald can be considered one of the many Blood Ties Easter Egg as he already made an appearance in one of the Dark Horse Comics (Lost and Found, Issue #9). In that comic Lara - as a child - took Sir Reginald's helmet and put it on while reading in the library. This leads to her musing now if she did put it back properly back then, which she actually did - in the comic we can see her stretching to reach high enough.
