Mid-century, painted, terracotta abstract figurative sculpture “La Testa” by Italian Futurist artist Renato Bertelli (1900-1974). Initialized “R. B. A-XI” The sculptor occupies a very unique place in the history of 20th century Italian sculpture: that of an artist whose worldwide renown is due not so much to his prolific figurative work as to his invention of a sculptural form devised in the course of his brief experience with Antonio Marasco's Independent Futurist Groups.
