Abstract: An easel-type loose leaf binder including a front panel, a rear panel, and a central panel which is disposed between the other panels, with fold lines running longitudinally the full length of the front and rear panels adjacent the central panel. The fold lines permit the front and back panels to be folded into a binder closed position. A transversely extending fold line extends across the front, rear and central panels to permit an upper portion of the front and rear panels to be folded back into an easel providing position. A rigid frame containing a plurality of split ring mechanisms is provided in combination with a relatively flexible backing strip which is located behind the rigid frame. A portion of the backing strip above the transversely extending fold line is secured to said rigid frame alone, while a portion of the backing strip below the transversely extending fold line is secured to both the rigid frame and to the central panel.
