It is usually an SOP in museums not to touch old aŕifacts, pictures, paintings, similar pieces because of the dirt or oils in our fingers/hands might leave marks and ruin them.
Sir suggestion lang, hwag po natin touch yung mga bagay bagay daahil nagkakaroon po ng prints, for preservation purposes, lalo na mga paintings, thank you po 🙏🏼 MAganda po ang pagkakalarawan ninyo sa casa, salamat po!
