Tops on my list if artists I appreciate is duo group Os Gemeos, a Brazilian 2-brother troupe of amazing-ness.
Here is a link to some of their work;
I was fortunate to visit the Montana Spray Paint Factory in Barcelona Spain this past spring and saw this mural first hand. Do you see how little I am in the face of their creativity?
On the other side is wife and fellow artists Nina. Another amazing one.
This is a site I found while researching for a design project. I love the appreciation for these images and typography. The work is iconic and amazing and I am constantly loving what is popping up in his collection.
Gotta love The Griffey.
