This recreated pan background is from the scene in which Alice sees (and follows) the White Rabbit. ("I'm Late!")
I particularly like the well-worn path, with its shaggy patches of grass dotted with daisies, and the beautifully rendered aquamarine water.
I especially love the brooding skies, equally stunning on both sides of the artwork, and yet rendered completely differently.
Gotta say it again... while the overall film may not have been Disney's most enchanting, it contains artwork that is among Disney's best.
