We have a pretty neat library of children's books started. I love them and have been collecting special ones for years, in addition to the classics. Above are some snippets of my absolute favorite design-oriented books, with colors and patterns and illustrations that can't be beat:
Sparkle & Spin - Ann & Paul Rand
Little 1 - Ann & Paul Rand
I Know a Lot of Things - Ann & Paul Rand
Henri's Walk to Paris - Saul Bass (recently re-released)
On a similar note, Clint and I have always wanted to collaborate and write/design some children's books. Maybe this is the year.
