Jerry Pinkney is a renowned American children’s book illustrator and writer — winner of numerous awards including the Caldecott Medal, Caldecott Honors and Corretta Scott King Awards, as well as awards from The New York Times, the Society of Illustrators and others. His illustration credits include over 100 books as well as editorial and institutional illustration.
Pinkney works primarily in watercolor and drawing media. His illustrations often have an appealing feeling of casual looseness that can conceal the solid composition and careful draftsmanship on which they’re based. I particularly enjoy his wonderful use of texture
The Jerry Pinkney Studio website is informative, and has some slideshows of his work in categories like Children’s Books, Illustrated Novels and so on, but it doesn’t make the best showcase for his work.
The best examples I’ve found are on the Norman Rockwell Museum’s Digital Tour of a Jerry Pinkney exhibit: Imaginings. There is an accompanying video of Pinkney speaking, along with other videos, in the “Media” section of the Pinkney Studio site (I can’t give you a direct link because the site is in frames, for reasons that elude me).
There is also a page devoted to Pinkney in the Artists’s listings of the NRM website, that includes some images.
You can find many of his books on Bookshop.org or Amazon.com (affiliate link).
