A 3D picture frame for making a 3D framed display. A mounted background picture is bent into a concavo-convex shape for adding a 3D effect to the displayed picture. A mounted bottom edge picture achieves a depth of the field and a wrap-around effect. A floating picture, which is preferably a self trimmed composite picture for bearing a customer's image, obtained without manual trimming process, is displayed in front of and spaced apart from the background picture. A created arch-shaped void space in this frame can house one or more magnetically held 3D arts therein. A toy platform can be installed to turn the 3D picture frame into a play-and-display station. An animated 3D art with a built-in insert will add "live" to the 3D framed display. All above contents can be mounted or removed without taking down the frame body from the wall.
