Abstract: Adjustable display apparatus comprising a pair of laterally spaced side supporting elements, each having an elongated front leg, an elongated rear leg, an upper section joined to the upper ends of the front and rear legs, and a lower section joined to the front and rear legs near the lower ends thereof. Elongated support bars are removably connected to the upper and lower sections of the supporting elements and are positioned near the rear legs of the supporting elements. A pair of support panels, such as aperture boards, are secured to the rear portions of the support bars to provide a mounting surface extending between the supporting elements. The support panels are overlapped at their inner ends and are removably connected together at their overlapped portions. Laterally adjustable display racks are removably mounted in vertically spaced relation on the support panels and are laterally adjusted to extend across the support panels from one supporting element to the other.
