I shouldn't be so amazed that it's hanging given that we ordered up an installer to be the one to deliver the picture, but I am comparing it to the mirror that the installer also hung today. This mirror has been sitting on my floor behind the couch for the past three years, save for a week of travel, and I'm in complete disbelief that it is finally hanging too.
Originally we were storing the mirror for my BIL who was working abroad. I was going to temporarily hang it but decided against that idea when I realized the mess it was going to leave on my wall when my BIL came to reclaim it.
When he eventually returned, he sent some pretty unprofessional moving men to pick it up. I am quite certain that they lost the bracket in their travels.
After having the mirror back in his possession for a week, my BIL sent it back to me as a gift, saying that his decorator deemed it an oversized no-no. As for the bracket, it never again surfaced. The mirror resumed it's position on the floor behind the couch where it hid for yet another year while I waited for our perpetually absent handy man to eventually show up and figure out how to hang it. I'm thinking that he's not coming.
This mirror is 7' x 4', and has a 3" wide frame made of lead. This kind of needed the uber strong bracket that it came with. Given that I had a guy coming to hang the new picture, I asked him if he would take a look at the mirror and see if he had anything to hang it with.
When the installer saw it, he let out a groan, complained about the weight and need for special materials, and eventually returned with another guy, a pile of metal, and many tools. It took about two hours for them to get the mirror on that wall, but it's up!
It's also earthquake proof and I will probably have to sell it along with the house one day, but I'll deal with that another time.
