On 28 June 2013, the group of patients from the Psychiatric Rehabilitation Ward of the Dr. J. Babiński Specialist Hospital in Krakow returned to MOCAK. The visitors viewed selected works from the exhibition Economy in Art, with the focus of their tour the mutual relationship between art and economics, and in particular the art market and the ways in which the artist’s intervention in an everyday object turns it into something of value. This phenomenon was also discussed in the context of art books; for this reason, the encounter culminated in those present joining forces to transform one of the publications into a unique, ‘priceless’ objects. The project was organised as part of the series Creative Economics for All.
