Probably just wouldn't seem as secure with the triangle hooks that are there for mounting. The back does say only to use with provided hooks, but it's a hand me down, they didn't come with it. Weird you think drywall anchors that come with a hook would be more common.

It is framed. But it has two triangle hooks on a hinge on the sides. It says do not use wire on back.
