Alfred Boman's *Air Castle* is a richly layered work that combines glue emulsion, acrylic, enamel varnish, and spray-paint on canvas, building a surface that feels simultaneously industrial and intimate. The interplay of these varied materials creates shifting textures and luminosities, evoking the ephemeral and dreamlike quality suggested by its title. Presented in an artist's frame, the work extends Boman's consideration of painting as an object, drawing attention to its own physical presence and construction.
