Voodou veve's are ritual symbols for invocation...Legba is coming!!

From VoodooShop: " Legba Derived from a great solar and phallic deity (Legba or Alegba) of Dahomey, the Loa Legba is one of the principal and most revered in Haitian Voudoun. Although now transformed to the aspect of an old man, he is still the powerful Guardian of the Centerpost, and the "Opener of the Gates" to whom first salutation is due in any ceremony of communication with the Loa. The main gateway to a hounfor is frequently denoted by two trees sacred to Legba." http://www.folkart.com/voodooshop/glossary.htm
