Landacre's artistic reputation began to emerge in the early 1930s with the publication of his book California Hills and other Wood Engravings and his first one-person exhibition in Los Angeles. He received many commissions for book illustrations; since he worked in a careful, deliberate manner, his large projects required years to complete. For thirty-one years the artist maintained a hand press in his home, allowing him to have total control over the printing of his designs. In 1939 he was made an associate of the National Academy of Design. The remainder of Landacre's professional career was balanced between teaching and illustrating books.
