Abstract
Abstract A vehicle rear view mirror includes a generally rectangular open frame formed from a cylindrical member. The frame is mounted for compound adjustment with respect to a mounting plate adapted for securement on a vehicle. A pair of mirrors are mounted within the frame for independent compound adjustment with respect to the frame to allow a wide angle rear view and to eliminate blind spots.
