No, in this case not completely undecorated as the ‘Racine’ series was always sold factory-decorated.

Next to hobbyists (and studios) that purchased undecorated whiteware, there were many that used ready-decorated items, making use of what they had at hand. A ready-decorated item could have per coincidence been at hand when needed or cheaper than having to send for (or wait for) a blank one.

Also hold in mind that items with factory-flawed decorations (“seconds”) or user-damaged decorations were also re-decorated. And then we have the so-called “decorator marriages”, sets made up from items of different manufacturers (often left over from breakages) which were matched into a new “set” as that was far cheaper than buying a new one.
