 Following his exclusion, Wolman continued to develop his own work, and he re-established links with the original Letterist movement and exhibited with them from 1961 to 1964.He devised Scotch Art in 1963, a process which consists in tearing off bands of printed matter and using adhesive tape to reposition them on fabrics or wood.In 1964, however, he split again from Isou's group, to establish the short-lived Second Letterist International with Jean-Louis Brau and François Dufrêne; thereafter, Wolman worked largely in isolation.
