@hakimirozman asked me if it does exist a design for the GSD badge.
As you can see, it does, thank to @rem289 who kindly thought of it. It is an “early design”, that is a prototype, which means it’s still subject to changes, but it’s most likely to remain pretty much the same in the end.
You will notice the badge has an octagonal form inside of it; there’s a clear reason for this — and you should have already seen an “octagon” somewhere in the comics. Will you be able to find it? :P
