It was my eBay find, which I had been searching over two years for.
Okay, so this might not seem very earth shattering, but this is the exact same design of badge worn by the Sixth Doctor in Revelation Of The Daleks.
As you know he always wore a cat brooch, and after serving him for several adventures, he retired his china tortoise shell cat and started wearing a different brooch in each serial.
What I have observed is that there is a almost standard set of illustrations of Marie (the character concerned), and the version seen in Doctor Who appears to be the most common.
That said, finding her on her own and not surrounded by some form of embellishment has been difficult.
I’ve seen versions with her name or phrase in a plaque; her siting on a throne; or even in a small group with her litter-mates.
The only times I have found the right design of her on her own, it has been either a vinyl sticker or a pair of earrings with loops at the top.
The brooch I’ve found comes from Disney Resort, Paris and the packaging has a URL at the bottom, so must be a relatively recent release.
It could well be it has been reissued, but I haven’t found it online at the given URL or on any other retail sites.
Eitherway I’m pretty chuffed to finally track one down and add her to my collection of screen-accurate cat brooches.
