Greek visual artist Kleomenis Kostopoulos, known professionally as KLE, has gained international attention for a large-scale mural dedicated to Maria Callas. The artwork, created in Kalamata, Greece, pays tribute to one of the most influential opera singers of the 20th century and reflects her enduring cultural legacy through bold visual storytelling and striking urban scale.
