Content:
"There is a strong sense of the absurd in the works of Alain Trez. His characters and animals are struck numb on wood, sometimes funny, melancholic at others, dreamy and touching in a profusion of colors and materials. Cartoonist by trade, Trez has allowed black humor to transcend his work for many years in French and foreign magazines and news media. Humor is always present in his work, colorful and tender, liberating the onlooker for an instant from 'this desperately serious world.' "
"Birds are his faithful companions: as mounts, friends or protestors, they provide Trez with the wings required to make us dream and escape from it all for a moment of happiness."

"The Little Knight's Dragon":
"A brave knight's son would rather shoot marbles than dragons. No wonder the kingdom is aghast when the little knight takes up the challenge of the fiery dragon who holds the little princess a prisoner. Equipped with only a pocketful of marbles he sets out in great confidence. All kindred spirits on this side of the page will nod knowingly when the great green dragon is suddenly entranced by these round colorful objects. After a friendly tame game, he accompanies the children back to the castle where he pursues his new hobby in the summer, and provides central heating in the winter."
