In an international design collaboration for US-based product brand Nalm Creative, Küntay Tarık Evren conceptualized and illustrated a comprehensive series of age-categorized doodle poster collections. Tailored to suit distinct developmental stages—ranging from playful, bold-lined graphics for toddlers to intricate, complex continuous line art for teens and adults—the poster series brings signature Doodlism storytelling into modern interior spaces. Evren developed curated visual themes for each age bracket, balancing artistic depth with decorative appeal. The resulting collection serves as both interactive wall decor and inspiring visual art, expanding Nalm Creative’s product line across the global lifestyle market.
