Muelle

Muelle was a trademark signature and design by Juan Carlos Argüello, Spanish graffiti pioneer (circa 1966–1995).

Around 1980, during the Madrilene cultural Movida, Argüello started reproducing the logo he had designed in walls and public spaces of Madrid. It consisted of the word Muelle (Spanish for spring), or an R with an enclosing circle (®) and a line in the shape of a coiled spring ending in an arrowhead. At first he used an ink marker, and later spraypainted his signature extensively around Madrid (and to a lesser extent, in other Spanish localities). In the eighties, he improved his technique, using several colours, wider borders, and 3-D effects.
