An altar, or pè, will often contain images (typically lithographs) of Roman Catholic saints. Since developing in the mid-nineteenth century, chromolithography has also had an impact on Vodou imagery, facilitating the widespread availability of images of the Roman Catholic saints who are equated with the lwa. Various Vodouists have made use of varied available materials in constructing their shrines. Cosentino encountered a shrine in Port au Prince where Bawon Samdi was represented by a plastic statue of Santa Claus wearing a black sombrero.
