John Fekner is best-known for his series of environmentally conceptual works consisting of words, symbols, and dates spraypainted throughout the five boroughs of New York in the 1970s. These "Warning Signs" pointed out hazards and dangerous conditions that overtook New York City and its environment during this decade. The project expanded in 1977, where Fekner created "Word-Signs." Through hand-cut cardboard stencils and spray paint, he began a crusade that was tirelessly concerned with environmental and social issues.
For Nuart 2017, John Fekner realized two conceptual outdoor works containing urgent and dramatic messages on contemporary society. This mural painted in downtown Stavanger says, "A clear view + A clear mind = A green world", suggesting a lack of vision results in environmentally detrimental outcomes.
