Portuguese street artist Add Fuel cleverly combines tradition and modernity in his murals, which borrow the techniques of a traditional style of Portuguese glazed tile work called azulejo. At a first glance, the blue, ornate glazed patterns of azulejo remain intact, but upon closer inspection, one begins to make out whimsical, cartoon-inspired characters in the classic designs. Add Fuel is also a commercial illustrator and toy designer, and the surreal creatures embedded in his tile work evoke a Pop-inspired aesthetic. He frequently juxtaposes clashing tile patterns to create images and text within the decorative motifs, resulting in many images hidden within images. Take a look at some of his recent work below.
