Seven years of drawings compiled into a 2,500-page book

The daily drawings are part of a personal project for his own website, and when Ruben reached a special milestone – his 2,500th creation – he came up with the idea to compile them all into a single book, including full-scale reproductions of the original illustrations.

All the publishers he approached claimed it was impossible as there are no machines capable of producing the necessary dimensions. But that didn't stop Ruben. He crowd-funded the project, searched for a binder to take up the challenge, and successfully launched "2500 days of RuSt".
