UNTITLED, LISBON

I got back late last night from a few days in Lisbon, which had much more to offer than deep blue skies I would have been happy with in London this summer.  The highlight was probably the Museu Coleção Berardo, which has a huge collection of modern art from many of the big names of the 20th century, including several pieces by Andy Worhol (not photographs of them), but there were so many by other artists who had named their work 'Untitled' that I was beginning to think that this had something to do with the museum's acquisition policy.  So I'm wondering if perhaps they might want to buy a print of this photo.  Or could the comma and the city in the name be just a little too much?
