I'll look into the regional side of things to add more to the article in regards to the plates. The edit adding that info was mainly just a quick one based on looking at the photos available - I didn't really look into context all that much...

Indeed, or perhaps they're actually not random and we simply can't see what they are due to the lack of high quality photos... :(
