Croatian 3D artist Filip Mrvelj has drawn the world largest 3D picture in Slavonski Brod, Croatia. The Guinness Book of Records has listed as the biggest picture of 750m2, while the picture dump made by Mrvelj almost twice as large – m2. For this drawing he needed 25 days. But for enter in the Guinness Book of Records, Mrvelj must call an expert from Guinness Book of Records, but currently his finances do not allow such a thing.
Fortunately, the image is made permanent colors in concrete, that will not wash off with the first rain or floods, so the Guinness commission can come and see it later if he collect required fund.
