The Vault Boy bobblehead figure is an item from the Fallout 3 video game. It permanently increases one of the 7 (S.P.E.C.I.A.L) statistics by one point. Pictured above is the Charisma Bobblehead, you can find it on the Vault 108 Cloning Lab.
This Charisma Bobblehead papercraft is from bluedragon, the photo above (from Killero) is similar but not related. "Nothing says pizzazz like a winning smile".
