Robert Opie Kit Kat Fridge Magnet

I picked this up from eBay a month ago from a seller in England. It's a Robert Opie collection Tin Plate Kit Kat Fridge Magnet. I have no idea who Robert Opie is. So, let me write you what it says on the back of the packaging.

The Robert Opie Collection
The world's largest collection of British advertising images, started by Robert Opie in 1963, provides a fascinating insight into the British way of life over the last 130 years. Featured many times in the media, The Collection now numbers over half a million items, and is continually expanding. A part of The Collection is open for public viewing in Notting Hill, London.

It'll be another neat addition to my collection. Cool, huh?
