Louise Brooks, and the German actress Brigitte Helm. Then briefly mentioned are Lya de Putti,
Bessie Love, and Anita Page. Perhaps an Italian reader could offer a better explanation, but I would guess that these other actresses are evoked in an article about Garbo in comparison to the renowned actress and elusive beautiful.
The paragraph on Brooks reads thus, in translation: "Louise Brooks, with bright black eyes, an impassive face and a supple body, has blossomed in a heavy atmosphere of contented passion, anguish, unsatisfied desires, feverish voluptuousness. She is, at times, cold and ardent, deadly and quivering: one would say the sign of vice."
The above article was, I believe, authored by Paul Rejac and originally appeared in Cinemonde, an French magazine. I will have to try and track that down. Brooks appeared on the cover of Cinemonde four times, and those four covers appear in Around the World with Louise Brooks.
The next clipping, which also depicts Louise Brooks and a few other actresses, also appeared in the December 1930 issue of Vita Cinematografica. The piece is a holiday greeting.
