Thomas Dambo, a Danish artist known for constructing giant, whimsical sculptures from recycled scrap materials and hiding them in forests around the world, has gained a massive global following. His troll-like creatures, made from discarded wood and trash, have become viral sensations, drawing visitors to remote locations. Now, after years of operating largely outside the traditional art establishment, Dambo is receiving recognition from the mainstream art world, with galleries and institutions beginning to embrace his work.
