The last time we posted a Fallout 3 Vault Boy Bobblehead, it was for the Charisma stat. I said that the bobbleheads increase your (S.P.E.C.I.A.L) stats by one point, what I forgot to mention was that it also increases your Skills by 10 points. Today we've got a bobblehead that increases your Speech skill, the Speech bobblehead. You can find this item inside Paradise Falls, head to Eulogy Jones' (head slaver) pad and you can grab it on a table next to a terminal.
This Speech Bobblehead papercraft is from bluedragon, the photo above (from Killero) is similar but not related. "Let words be your weapon".
