Don't ask me, Chris! I can't find any references at all, so I'm perfectly happy to go along with CND, which isn't in use by anyone alse, anyway.
As we like alternatives these days, I've renamed the logo I posted before, which is as it appears on the aircraft, and also done the Corendon Vliegvakanties logo which adorns their web page which is titled "Corendon Dutch Airlines". Take your pick
