[1] Original members of ANK' 64 included students of the art institute, Malle Leis, Tõnis Vint, Jüri Arrak, Kristiina Kaasik, Tõnis Laanemaa, Marju Mutsu, Enno Ootsing, Tiiu Pallo-Vaik, Vello Tamm, and Aili Vint.
The small group aimed to hold exhibitions outside the official system, to change theoretical ideas, and to organize private seminars on modern art.
[1] Leis preferred working in abstract in the early sixties, but eventually developed an interest in pop art towards the end of the decade.
Leis' was highly influenced when being part of ANK '64, and mostly worked with an abstraction in the beginning of her career, but quickly moved to pop art style by the end of the 1960s.
[3] Leis began to paint large and bright flowers and vegetables in the 1970s, occasionally adding in human figures or horses.
Leis' 1972 painting Sunlight Triptych shows striking red poppies and yellow daffodils against a flat blue background.
The colorful flowers form an idea of life and happiness, but the head in the corner has been reduced to an object, simply gazing into space with an emotionless stare.
