Original storyboard (5.75” x 6.5”) by Chuck
Jones, mixed media (graphite, watercolor & colored pencil) on MGM
storyboard paper for his 1970 television special, "Horton Hears a Who!"

Preliminary work began on the second Dr. Seuss
and Chuck Jones collaboration before their “Dr. Seuss’ How the Grinch Stole
Christmas” even aired.  This included not
only pre-production watercolors by Jones, but also layout designs by the
inimitable Maurice Noble.  However, it
would be four more years before their labors would bear fruit and the special
would make its premier, March
19^th, 1970 on U.S. television.
