“…Based on this assumption, the issue of "hidden histories", the degree and the way of presence or absence of the history of different people and social groupsincluding disabled peopleis an important topic of discussion within museums in terms of inclusion and equality (see, e.g., Allday, 2009;Delin, 2002;Dodd, Sandell, Jolly & Jones, 2008;Martins, Semedo, & Camacho, 2018;. The social model of disability has been the basic theoretical framework within museums not only about accessibility but also about the ways that disabled people are portrayed, presented, under-presented or mis-presented within museums" collections even if the latter happens unintentionally (see, e.g., Sandell, Delin, Dodd & Gay, 2005). Similarly, in the frame of the social model of disability, arts are not considered as a therapeutic tool but as a cultural process and product (Oliver, 1990) placing the emphasis on social, political and cultural aspects and challenging ableist discourse and ideologies (Eisenhauer, 2007).…”
