At that time, I was strongly style-conscious; I thought that first of all, the series must have stylistic unity. The woodcuts I did at that time were only studies for the style of the series.
Working on these early woodcuts, I ran into new difficulties, and after some time, having accumulated so many difficulties and with them so much self-doubt, I felt that after a year of intense work, that I could go no further. Totally discouraged, I gave up not only my project for a portfolio of trees but also the woodcut itself for several years.
My doubts about woodcutting contaminated my painting. These doubts, together with poor working conditions, difficulties in getting art materials, and the numerous other difficulties of life in postwar Europe, forced me to give up painting as well for several years.
In 1949 I came to the United States. I settled in Saint Paul, Minnesota, where I got a job as a designer at Brown & Bigelow. After many difficult years in Europe, I was happy to begin living a stable life.
