Snow Globe

The snowglobe is the Fallout: New Vegas equivalent of the Vault Boy Bobblehead from Fallout 3.

Effect
As mentioned by Chris Avellone, the snowglobes will have a similar effect to the bobbleheads in Fallout 3.

They will not, however, provide a permanent SPECIAL or skill increase such as the bobbleheads provide. They will provide a different, as yet unknown, positive in-game effect. It has been confirmed by an Chris Avellone that there will be a Yellow Snow Globe that will provide an unknown boost to statistics of the playable character.
