According to his widow, Stubbing composed concrete poems in the late forties and early fifties both in English and Spanish. However, he is best known for his palm print abstract paintings. He might have became influenced in concrete poetry by Mathias Goeritz with whom he knew in the School of Altamura, Spain in 1949-1950. However, Goeritz's concrete poetry was published over a decade later from the Spanish experience. An original concrete poetic collage and typing "Poema Vociferado" c.1949 is held by the Sackner Archive. -- Source of annotation: Marvin or Ruth Sackner.
