These are beautiful and very well made.  They can hang horizontal or vertical.  I chose to hang them side by side interlocking them by hanging the first horizontal and the second vertical.  At first, I wasn't sure about having all of the pictures the same size, but now that I see it, I really love it all.  The pictures are so easy to change for updating in the future.

Fabulous Value and Beautiful.  The 9 frames or in and of themselves a piece of art the way that they overlap each other.
I had to put hanging wire on the D rings in order to hang the frame the way I wanted.  Hanging Wire should be included.
