Guys, am I missing something here?
Surely the Centenary logo is specific to that event and has little to do with the Morgan Motor Company logo (and their revision of the logo)?
While I recognise the two are co relational, this is only to an extend. I believe this is a little like our Olympics logo (awful as it is!), it is an interpretation of an established logo but is only specific for that particular event. It references the parent but must equally stand on it's own.
Forgive me if I'm being slow or missing the point!

(and if I am, feel free to explain the points I'm missing!... just speak slowly and use lots of pictures!
