[1] Gallery devoted to Hasior's work has existed since 1984 and is situated in the interior of the 'deck-chair rental' by the Warszawianka Hotel, a building that was built prior to World War II when Zakopane was an antituberculosis resort and bed rest in the open air was a common form of treatment.

[1] Officially, Hasior's Gallery is a branch of the Tatra Museum, which the artist enriched with a "dowry" of around one hundred of his works.
