Annoyed at the cold reception his wife Sarah Bixby Smith's realistic still lifes had received from an art exhibition jury, Jordan-Smith sought revenge by styling himself as "Pavel Jerdanowitch" (Cyrillic: Па́вел Жердaнович), a variation on his own name. Never having picked up a paint brush in his life, he then painted "Yes, we have no bananas", a blurry, badly painted picture of a Pacific islander woman holding a banana over her head, having just killed a man and putting his skull on a stick. In 1925, Smith entered the banana picture under a new title of "Exaltation" in New York's "Exhibition" of the Independents at the Waldorf-Astoria. He made a suitably dark and brooding photograph of himself as Jerdanowitch, and submitted the work to the same group of critics as representative of the new school, "Disumbrationism". He explained "Exaltation" as a symbol of "breaking the shackles of womanhood." To his amusement, if not to his surprise, the Disumbrationist daub won praise from the critics who had belittled his wife's realistic painting.
More Disumbrationist paintings followed: a composition of zig-zag lines and eyeballs he called "Illumination"; a garish picture of a black woman doing laundry which he called "Aspiration", and which a critic praised as "a delightful jumble of Gauguin, Pop Hart and Negro minstrelsy, with a lot of Jerdanowitch individuality"; "Gination", an ugly, lopsided portrait; and a painting named "Adoration", of a woman worshipping an immense phallic idol, which was exhibited in 1927.
Since 2006 there has been held a yearly painting contest in memory of Paul Jordan-Smith and the disumbrationist school of arts: the "International Pavel Jerdanowitch Painting contest". The winners were Kurt Hinterbichler in 2006, kunst/gruppe olga in 2007 and Olga Krolik in 2008.
