You gasped as you pulled out a giant portrait, that had 12 faces of boys on it.

You saw their names also painted into the portrait and your fingers gently slided across the dusty portrait. You looked down and stare at it in awe, it was wonderful. 

Very pretty and the boys, there was only one thing you could describe them.
