The frame is a 4X6 that has a ledge on the back so that when you stand it upright your picture is displayed at a bit of an angle (looks like a backwards L when viewed from the side...). With the phone memo pad, I actually have the frame upside down so that the frame makes a writing surface and the ledge tips it up...
You can find these frames at Rite Aid, Walmart, Target...
Does the above description make any sense at all?
