A display system for displaying display members such as numbers, letter or other indicia, e.g., for use in signage for displaying the price of gasoline on the premises of a service station. The display system of the invention utilizes magnets to facilitate easy substitution of display elements. The display system has a support surface supporting at least one securing member, which is preferably a V-shaped member having an upwardly facing recess. A magnet is provided proximate the securing member. A display member is provided with at least one secured member, e.g., an inverted isosceles triangle having a downwardly facing apex for complementary engagement with said upwardly facing recess of the securing member. A metallic mass is located proximate to the secured member for magnetic engagement with the magnet proximate the securing member. An extendable arm is preferably provided for manipulating the display members when the display members are mounted high off of the ground. Although the securing member is discussed as being located on the support surface, it should be understood that secured member may located on the support surface and vice versa. Similarly, the locations of the metallic mass and magnetic mass may be switched and still fall within the contemplated scope of the invention.
