A monumental study in geometric precision, this work presents Christo's vision of a towering mastaba structure composed of stacked oil barrels, rendered through a dynamic interplay of charcoal, gouache, pen, and graphite. The drawing captures the artist's signature approach to large-scale temporary installations, balancing architectural grandeur with the intimate textures of mark-making on paper. Conceived for the grounds of the Rijksmuseum Kröller-Müller in Otterlo, the work reflects Christo's lifelong fascination with transforming landscapes through bold, utilitarian forms elevated to the realm of public art.
