A delicate preparatory sketch rendered in pencil on translucent tracing paper, this study reveals Remedios Varo's meticulous creative process as she mapped out the surrealist imagery that would culminate in her finished work. Ghostly, precise lines capture her characteristic blend of mysticism and architectural fantasy, with figures and forms emerging from the fragile, luminous surface of the tracing paper. The work offers an intimate glimpse into Varo's imaginative world, where scientific curiosity and dreamlike narrative intertwine in careful, deliberate strokes.
