"The First Book of Christmas Joy" by Dorothy Wilson, illustrated by Mary Ronin (1961)

MARY RONIN (1912 - 1992) was born in Sycamore, Illinois, to Jas Ronin, a horsetrainer and his wife Blanch Darling, and spent her childhood in Nebraska. After studying art at Omaha University, she arrived in New York, age twenty-five, and in June 1938 started working the advertising art department of Bloomingdale’s. From Bloomingdale’s, she moved to Young and Rubicam, where she took a position as an art director, one of the first female art directors in New York. After seven years with the advertising agency, she took a sabbatical year in France, returning to Manhattan in 1953 to freelance. Ronin worked thereafter as a book illustrator, and she is associated with a number of works published between 1959 and 1971.

"The Reindeer Book" illustrated by Aurelius Battaglia (1965)

AURELIUS BATTAGLIA (1910-1984). He was the son of Sicilian emigrants and he grew up in the city where he was born, Washington DC.nHe graduated from the Corcoran Art School of Washington Dc., where worked as a teacher. He graduated as one of the Corcoran's most promising students, winning $50 in a Corcoran-sponsored art contest.
In 1934, the Public Works of Art Project commissioned Battaglia to paint murals in the children's section of the library in the Mount Pleasant neighborhood of Washington where he resided. The result was a stunning, whimsical panorama of anthropomorphic animals at play. It still hangs in the alcoves of the building's second floor. 
Battaglia migrated west in the late 1930s and worked for the Walt Disney Studios from 1937 to 1941. He contributed most notably to Dumbo, Fantasia, and Pinocchio and is credited as one of the writers of the latter. In the mid-1950s, Battaglia joined United Productions of America, a studio staffed by some of the industry's most accomplished, forward-thinking animation artists. Perhaps his most outstanding UPA contribution was the short film The Invisible Moustache of Raoul Dufy. Battaglia directed the film, which was nominated for a BAFTA award.
Battaglia was also a prolific children's book illustrator. His picture book work in the 1950s and 1960s differs significantly from the deco-inspired circus animals of his depression-era murals. They feature bold, solid colors and striking, stylized pen and brush work indicative of the looser, more abstract mid-century cartooning style that he helped pioneer. Notable examples include "Cowboy Jack, the Sheriff," "The Fire Engine Book," "Little Boy With a Big Horn," "When I Met Robin," "Captain Kangaroo's Read-Aloud Book," and "The Fireside Book of American Folk Songs." He contributed to the Childcraft book series published by Field Enterprises. 
In the 1930s, Battaglia worked in a flowing, deco-influenced, organic style informed by classic European illustration. His later children's book and animation work was emblematic of the radical, more abstract stylization prevalent in the 1950s and '60s, a trend he helped to establish.
