Bartek Elsner is a Berlin-based multi-disciplinary designer and art director with the focus on digital communication and interaction, but he’s also known for his structured paper pieces, calling himself “one of those cardboard artists”! He has built incredible cardboard objects including a replica of a human heart, a motor saw, a life-size fireplace and a gigantic Ghettoblaster, which was commissioned by the International Radio Festival in Zürich back in 2012.
These are works by a man with a strong imagination and even stronger understanding of the craft and the material. Each object is hand made by Elsner himself and has been showcased in multiple exhibitions. Besides his day job as an Art Director, he spends his free time crafting these stunning cardboard pieces. Some are commissioned by commercial clients, but most as just Elsners own work. To keep up to date with his cardboard art, check out his PAPER BLOG here.
