Not only is he one of the artist behind the "Epos-Visa 100 Card Design" project ( 2 prior entries ). But Joao has also quite the graphics/illustration portofolio with a collection of great pieces (like the one pictured above).
"The Great Pyramid" mixed with colorful details in the middle and light metallic undertones in a black background ... what else can you ask for? Simply on point!
