The stylized face of opera singer Lina Cavalieri defines the 'Tema e Variazioni' series by Fornasetti, appearing across a selection of signature pieces. In the hand-decorated rectangular porcelain 'Tema e Variazioni N.137' ashtray, Cavalieri's face appears in black and white on the round porcelain table accessory, with a somber gaze and a flower at the corner of her mouth —  a detail that captures the playful Fornasetti spirit. Products of fine artisanal craftsmanship, designs may display minor distinctions that make each one unique.
