A frame for attachment to a truck panel or a wall for holding a banner having a top base plate, a left side base plate, a right side base plate, and a bottom base plate. After the top of the banner is aligned and duct taped to the top base plate, the banner can be accurately cut to size by simply inserting a blade through the banner and into cutting groove on the base plates which becomes guides for the blade. No math is required. At least one yieldable member having a high coefficient of friction is coupled to each base plate and a cap plate is located on top of each base plate to lock the edges of a banner to each base plate by pressing on the yieldable members on each base plate when the banner is located on top of the yieldable members.
