I thought it would be easy to find out who designed or manufactured this floor lamp since not many Designers worked with marble. But since I could not find any besides Arco by Flos from A&PG Castiglioni, Ponte by Gruppo Artditi or others in similar styles like linea by Nanda Vigo. So who has a clue? I m curios to know! thank you for your interest and time.
