This papercraft is The Jagged Crown, a unique heavy helm, located at Korvanjund, and an ancient relic that has served as a symbol of leadership and power for kings and queens of Skyrim since the First Era, based on the game The Elder Scrolls V: Skyrim, the paper model is created by ZombieGrimm. The finished model measures about 16 inches tall.
The Jagged Crown can be kept by reverse pick-pocketing it to either Hadvar or Ralof after the crown is collected but before the quest is completed. Although the chance of success will show 0 percent, it is possible, but may require several attempts. The faction sided with at Helgen must be joined for the exploit to function properly. Once the quest is complete, the crown can be pickpocketed back from Hadvar or Ralof during one of the missions to Retake Fort or after the Civil War in Riverwood. Using means of paralysis, or boosted Pickpocketing improves the chances of recovering it successfully. [Source: wikia]
