Wanda Hazel Gág was an American artist and writer, best known for her children’s book Millions of Cats, which is the oldest American picture book that is still in print. Millions of Cats was written and illustrated by Gág. It was published in 1928 and won the Newberry Honor award in 1929. The book is known for its hand-written text, its black-and-white illustrations, and for its double-page spread. Born in New Ulm, Minnesota, Gág was recognized for her appreciation of rural landscapes, still lifes, and family home life. From the 1920s to the 1940s Gág was known for her talent in lithographs, woodcuts, and other types of prints. These prints best demonstrated Gág’s ability to play with light, shadow, shapes, and lines, as seen in her dramatic shadings juxtaposed to bright illuminations. The 1920s also saw Gág working with sandpaper.
