At first, Teitelbaum painted his own form of portraits featuring
expressionism, then landscapes of various regions in Canada. His style became increasingly abstract throughout his years of painting, going through many changes, among them single
Zen-like improvised gestures on unprimed canvas. By 1967, he critiqued modern art, then in 1973, he made paint skin constructions, of
acrylic paint peeled away when dry from
polyethylene sheets to make
collages. He then turned to painting exuberant landscapes. That he turned from abstraction to representation in some ways resembled that of other artists of his generation such as
Duncan de Kergommeaux who also turned away from abstraction to depicy landscape. == Personal life ==
