Mural Mosaic is a process invented by artist Lewis Lavoie that takes individual paintings and places them in a specific order to create a large painting. The first Mural Mosaic was created in 1997 for a retaining wall next to an art gallery in St. Albert, Alberta, Canada. Five years later, in 2004, Lavoie took his process and involve other artists. During a 24-hour "paint-a-thon" to raise money for a local charity, Lavoie pre-prepared panels with color tones and shapes, then using the color guidelines on the prepared panels as inspiration, artists created a painting using their own style. When all the panels were reunited, the final image was a success.
Lavoie and his partners Phil Alain and Paul Lavoie began the Mural Mosaic journey to bring communities together using their murals as examples of "Unity through Diversity". This is represented by bringing the uniqueness of individual creative styles together on numerous panels to create one united image. The most unique aspect of this artistic process is that artists are given an individual panel with the freedom to paint what they want within the "theme" of the mural subject, however, the final image created by Lavoie is kept secret until mural unveiling.
