Early in 1969, he was commissioned to design and execute his largest free-standing sculpture. “The Obelisk”, commemorating all the Arts – performing, visual, etc., stands 60’ high and weighs 50 tons.  It consists of a central tapered tower form of white cast concrete, around which eight heroic sculptures of ferro cement are cantilevered.  These  ferro cement sculptures are sheathed in most part with brass and bronze, contrasting with the precast tower.

Intrigued by the development of ferro cement in the boating industry, using these techniques and procedures for this thin shelled reinforced concrete, Vrana developed a method of fabricating large monumental sculptures that were light and very durable.
