This artist's book, published by Les Éditions du Livre in Paris, represents a collaboration between Jean Dubuffet and the poet Guillevic, uniting visual art and poetry in an intimate, handcrafted format. Stamped number 131 in black ink on the title page, this copy belongs to the primary edition of 150, part of a total run of 172, underscoring its collectible rarity. Dubuffet's raw, unrefined aesthetic sensibility finds a natural counterpart in Guillevic's spare verse, the two artistic voices merging to explore the elemental theme of walls as both physical barriers and metaphorical boundaries.
