Vault-Tec Bobblehead (Fallout 4)

Vault-Tec bobblehead figures are promotional Vault-Tec items in Fallout 4.

Background
Vault-Tec bobbleheads are found on the eastern side of the former United States, throughout the Capital Wasteland. Bobbleheads were exclusive Vault-Tec merchandise available to executive-level employees of the Vault-Tec Corporation. They were also offered as a gift to individuals who had been accepted into vaults. This sounds really cool....but where does this information comes from? I don't see a source cited?

Characteristics
Each bobblehead increases a corresponding S.P.E.C.I.A.L. stat permanently by one, or grants a permanent perk. They can be stored on a bobblehead stand which can be crafted at any settlement. A stand is also present in the room in Vault 81 upon being granted to the player character.

Taking a S.P.E.C.I.A.L. bobblehead while the player character's stat is at 10 allows that stat to increase to 11. As the bobblehead counts as a stat gain, if one was below 10 before picking it up, they cannot level that stat to above ten via normal methods.
