TORONTO -- For prolific picture-book artist Warabe Aska, art always comes first and text second. "Imagination and inspiration are very important to me," he says.

"The World of Warabe Aska, Poems for the Earth: Imaginature" is the artist's 25-year retrospective collection, with works culled from over 20 solo and collaborative books.

The 120-piece exhibition is a testament to the artist's sympathy for the environment. Aska's brilliantly colored oil paintings are painstakingly meticulous and fit human and animal life together like pieces of a puzzle.
