I remember that picture from a street in Prague. I wouldn't be able to track it back, to be frank. It was in an artsy bohemian street, along the Vltava. But I think it fits to the theme. This sculpture looks blank, cold, on the outside. But nostalgia can indeed turn us into a column of salt, but inside we are burning up from the memories and the souvenirs and the past which we harbour inside of us.
