This survey presents the work on paper of Charles Arnoldi (born 1946), a nationally renowned artist based in Los Angeles. Arnoldi has been described as an artist who "draws in space" to create his unique assemblage works of art. Throughout his long career he has been fascinated with shape and pattern as they apply to advanced formal concerns, from his 1970s paintings made entirely of natural forms, to his current geometric work. Internationally renowned architect Frank Gehry has said that "the maturing Arnoldi has a secure color sense and the ability to work at large scale as well as to produce tiny, exquisite watercolors." Gehry cites Arnoldi as an influence in his own work, stating that "this is an artist whose best is yet to come, who is still experimental and still willing to risk."
