Believe me, I can perceive it...I work for an Insurance Agency ;) I can see the liability risks all over the place but as *Bonfire said, the glass is already being shipped in framed prints.
I guess that's why I have a job, for all those wild liability risk takers!
*Bonfire, the deeper I get into this, that's what I'm beginning to realize. The display & creative lighting possibilities could be quite beautiful.
