This break into reflex and subconscious is no longer sufficient. He had lost through his practice in New York the empathy which he maintained in Rome with the emotions from all periods. He then performs a synthesis between the Blackboard and the antique graffiti, altogether reintroducing color which is an improvement and erasing which is a decay.
On November 10, 2004, Christie's sold for $ 5.4 million including premium an oil, wax crayon and graphite on canvas 161 x 195 cm made in Rome in January 1971. The entangled loops in shades of gray are structured in wide lines such as in the blackboards of the previous years, but the clarity of the line is erased over the entire length while the regions empty of proto-writing remain intact.
On November 10 in New York, Christie's sells as lot 17B a canvas 148 x 196 cm painted in similar technique, also dated 1971 but not located.

The estimate is not published.

It has become virtually imperceptible by the domination of a network of colored lines, launched as a waterfall on the entire available surface with the exception of a reserve at the top left corner.
Several years before, at the time of his pornographic inspiration, the Roman waterfall was one of the favorite themes of the artist. It was a flow that looked homogeneous but actually consisted of a texture of multiple graffiti.
