There was another art work attack in Stockholm. Hopefully no damage was done as the piece was covered in glass. See link to article below.
I understand that many of us - me included - like to carry a water bottle and snacks or other items with us while we are out sightseeing during the day. However, our desire to have our "stuff" with us at all times does not outweigh the museum's responsibility to safeguard these precious treasures for posterity. Rules such as checking bags at the door or not allowing water bottles are in place to help them do so. I sometimes see posts on this forum asking if these rules will be enforced. We all should hope that they will be.
