Houben Tcherkelov, (Bulgarian: Хубен Черкелов; known as Houben R.T.; American, born in Bulgaria on January 23, 1970) is a painter and experimental artist who lives and works in New York. In his early photographs, film, and installations post-communist Bulgaria and Bulgarian art is a recurrent theme. In his more recent work, Tcherkelov paints images from American and other national currencies using impasto, glaze, foil, acrylic and watercolor techniques. In all of his work the artist seeks to suggest the way in which symbolic images legitimize national power.
