In the late 2017, Dancing House Gallery presented a large retrospective exhibition of Josef Lada's works. The show entitled the Sevens of Josef Lada served as a reminder that 130 years have passed since the birth and 60 years since the death of this major Czech artist. More than 40,000 visitors came to see the show. The communication campaign provided by PIARISTI included media partnerships, PR activities, celebrity PR, and social network administration.
