It is a just display base, and a very nice one (better than anything I have done so far). Nice but irrelevant.

It was the miniatures what they were interested in (and wanted to show in White Dwarf).

If they want to show a nice army made by a customer they might not ask every single detail about it. Especially about the display base. for example do they ask which kind of wood it is, and what thickness?
