I need to write a eBay advert description for a advert to hopefully go Viral

Num. of words: 500
Topic: Royal Baby
Tone: Witty/Sharp
Extensive research needed: no
Extra notes: Please take the time to Google Royal Princess Plate 2013, that's our plates :) we have decided to keep most of them and auction a few off to good causes, first being Great Ormond Street Hospital Children’s Charity, we have a advert on our website that has gone viral but now want the same magic for the eBay auction. We want to get across the fact the plates will be collectable, there rare well ish if we do not sell all 5000!!, your welcome to put any funny spin on them that you feel fit.

Please try to fit the advert around the style of the website advert, full details will be given to the winner as well as a nice list of news sites that have featured the story to date.

Thanks
Karl.
