The Slant Memorials are ages old and very common in cemeteries throughout the United States. The slant memorial is an upright with the face of the memorial cut at an angle. These memorials can stand alone without a base because they are generally 10" thick. Often a family will put a sub-base under the slant so that they can put granite flower vases on the sides. Most cemeteries require a granite base to sit under flower vases.
