In this paper the author sketches the coming into being and the development of his father’s collection. Thirty five years ago, Leszek Macak acquired his first items of folk art as decoration for his newly built house. Soon his collector’s passion made itself felt, directed in particular towards the folk art of the Polish mountain regions. These recollected episodes illustrate Macak’s tireless efforts to expand his collection as well as his sincere love and admiration for the artists. A chance event resulted in a significant change of focus for the collection, from folk art towards art brut. Finally, some further vicissitudes of his father’s collection are mentioned.
