Publisher's description:
Zoro is a little boy in 17th-century Italy, long before airplanes flew in the sky. But Zoro is also an apprentice to the artist and inventor Leonardo da Vinci—and Leonardo is experimenting with a revolutionary flying machine! This is a title in Barron's Anholt's Artists Books for Children series, in which author and illustrator Laurence Anholt recalls memorable and sometimes amusing moments when the lives of the artists were touched by children. Anholt's fine illustrations appear on every page and include reproductions of works by the artists.

From the back cover:
Anything is possible in the studio of Leonardo da Vinci - painter, sculptor, musician, and scientist. But what is the extraordinary secret locked behind the doors of his mysterious workshop? When Zoro, the young apprentice sneaks inside, he sent soaring into a thrilling adventure.
Complete with reproductions of Da Vinci's work, this is another inspirational story from Laurance Anholt's bestselling series, celebrating some of the world's greatest artists and the real children who knew them.
