From 1944 to 1946, Doubleday published three picture books written by Brown under the pseudonym "Golden MacDonald" (coopted from her friend's handyman) and illustrated by Leonard Weisgard. (Weisgard was a runner-up for the Caldecott Medal in 1946, and he won the 1947 Medal, for "Little Lost Lamb" and "The Little Island". Two more of their collaborations appeared in 1953 and 1956, after Brown's death.) "The Little Fisherman", illustrated by Dahlov Ipcar, was published in 1945. "The Little Fur Family", illustrated by Garth Williams, was published in 1946. Early in the 1950s, she wrote several books for the Little Golden Books series, including "The Color Kittens", "Mister Dog", and "Scuppers The Sailor Dog."
