Pavlos employs concepts of new realism and pop art in his work. By assembling paper strips cut out from posters and metal wire, he creates characteristic compositions featuring ties, jackets, coats and shirts hanging on chairs, racks or on the wall, curtains, trees, pillars and still lifes, landscapes, seascapes and fields, where initial impression and end result depend on the color play and the way in which the material is glued together. In similar ways, he has also created environments, while his artistic activity also includes two happenings.
