[1][2] Self-taught,[3][4] Peticov's approach is based on systematic personal research in the history of art and its integration into avant-garde artistic movements in the second half of the 1960s.

[1] In 1967, together with artists Aldir Mendes de Souza and Gilberto Salvador, he founded the group Vanguarda Jovem no Arena, participating in several exhibitions.

During the 70 days he was at Carandiru, he continued to draw and paint, becoming friendly with a fellow prisoner, Giuseppe Baccaro, an Italian intellectual and art merchant, who was arrested for possession of a joint.

[9] He was interviewed by Antônio Abujamra in 2016 on the TV Cultura interview program Provocações and stated: "In my hand there appeared a large amount of lysergic acid, which was perhaps the most important invention of the 20th century, because it was the opportunity to have in my hand, in my pocket, or in my wallet the ticket for the most important trip that a person can have in his life, the trip to his interior.

He has also produced audiovisual productions, among them: Having moved to Milan in 1972, Peticov bought a copy of Aldo Montù's 1970 book Φ = 1.61803398875... Appunti ed annotazioni su Natura e Geometria - Progressione Aurea e forme pentagonali.
