A display stand for a laptop computer has an L-shaped spine supporting the computer. A T-shaped upper advertising substrate holder can be slid into the vertical leg of the spine in one of multiple orientations, i.e., with the cross-bar of the T horizontal to the ground or vertical to the ground on either the left side or right side of the computer, as point of sale (POS) physical constraints demand. In all orientations of the upper holder, an upper advertising substrate is supported by the upper holder in a vertical orientation. A T-shaped lower advertising substrate holder can be slid into the horizontal leg of the spine to support a lower advertising substrate in a horizontal orientation.
