'Leblancs so-called informal painting is the result of a tension, an interaction of strict rules and creative freedom. He has maintained a system which is in a certain sense very rigid, but unceasingly tries to exceed it with inventiveness. He constantly appeals to the flexibility of the frames limits. The limitations are modified to become possibilities. Precisely this tiresome way of working has led Walter Leblanc to create a disturbing, ever intriguing work in which rhythm, order, the play with series and light, and human perception occupy a central place. I admire the perseverance, motivation and extreme logic that Leblanc has applied in the course of the years to his work, which fluctuates between abstraction and figuration.'
