The two examples of Bra(a)tz coats of arms shown on the homepage are provided as decoration to the site and not necessarily the legitimate coat of arms for all with the surname of Braatz or Bratz. The composition of these symbols are legitimate and they do belong to German Bra(a)tz families who had the legitimate right to display them. The difference being that not all those with the same surname has the legitimate rights to them, just those who were granted them by the royalty of Germany and their descendants.
The heraldry of the blazon, the graphic itself, is recorded as a written description and not an actual drawing. Thus, both of the examples of the page represent the same blazon, each interpreted just a bit differently in the actual composition of the graphics.
While it is not necessarily owned by all those with the same surname, these symbols are great fun and can be used in various ways by those of us who are named Braatz, Bratz, and the like. These blazons are also used in many commercial enterprises, putting them on plaques, drinking glasses, shirts, jackets, and the like.
