How To Hang Your Joyfully Said Wall Art

Hi, I love my art that I received but I wish I was told I would have to have a hook or some way to put the art on the wall. There is nothing on the back and just having a screw in the wall it will slide off and fall (I tried). I will have to send it to Hobby Lobby and have them add either hooks or wire to hang it.

Just thought you should know. Thanks!
