A sign system is provided. The sign system has a hoisting mechanism for moving a sign between an access or servicing position near ground level and an elevated display position. The sign system includes a first set of guide members and a second set of guide members and a drive system. Each guide member is generally tubular. The guide members of each set are connected together for telescopic movement. Each set of guide members includes an outermost guide member and an innermost guide member, one of which serves as an anchor guide member and the other of which serves as a sign supporting guide member. The sign supporting guide member includes at least one connector for connecting the sign thereto. The anchor guide members of the first and second sets of guide members are fixedly connectable in a generally vertical orientation to a wall or other vertical support means in horizontally spaced relation to each other such that the first and second sets of guide members are extendible downwards to move the sign to the access position and retractable upwards to move the sign to the display position. The drive system is operatively connected to the first and second sets of guide members for selectively moving the first and second set s of guide members between the extended position and the retracted position.</ SDOAB>
