that's right karen i'm here with christine mcclain she was the manager of the east side gallery at the time of its creation christine i just saw a little clip in the film behind us an artist saying for her the wall was always a nightmare and being able to paint on it transformed it into a dream what's your reactions about 30 years later well our feeling at the time was that we transformed the world that we healed this part of the will is not the same as the wall and then our styles which is a reminder of the terror this was actually more the feelings that people had of joy wishing for something better hope for a better world and those are the emotions that the artist put into most of the paintings. you could help create this project at a time when people were tearing the wall down people didn't want to see the wall anymore why did you want to preserve this 1300 metre stretch of it i think is really important to me also it was really important to preserve a piece especially this size because how can you imagine if you were not even born then or if you didn't know what the wall was like
