Vakalo received his initial artistic training in Constantinople under Lysandros Prasinos, who taught him painting and miniature art.
[1] Influenced by surrealism, he also studied scenography at the Theatre de l’Atelier under Charles Dullin and apprenticed with scenographer Ladislas Medgyes.
During the German invasion in 1940, Vakalo was forced to relocate to Greece, where he continued his work in scenography and costume design with local theaters.
[4][5][6] Vakalo was a member of the Chamber of Fine Arts of Greece (EETE).
[7] Vakalo's painting style is characterized by a unique personal hyperrealism, where line and color play primary roles, often in soft tones, and a strong decorative inclination is evident.
