It might seem hard to believe at first but these works by German artist Martin Senn are not contour line drawings. They are, in fact, wire sculptures. Senn's three-dimensional figures against a white backdrop certainly resemble ink or marker illustrations that have quickly been scribbled onto one's own sketchpad but there's nothing quick or simple about them. Upon closer inspection, one can see the number of loops, knots, and pieces of wire that have been used and manipulated to project each object. Senn tackles the construction of ordinary items ranging from the retro rotary phone to the present-day vespa. There's something very playful about his works that compose outlined versions of invisible things.
