Can you tell me whether such a scarf would be available through the website. As I am bedridden, it would be impossible for me to visit an Hermès boutique, sadly.
I believe the 90 Bday one was only available via New Bond St store (not online). I believe it was also a charity scarf with all the money going to a horse charity (not just the profits). There were very few made but they don't seem that expensive on the pre-loved market.
Not sure if the Diamond Jubilee was online elsewhere (can someone from Oz or Canada chime in?). I bought mine at the Windsor Horse Show - where later, I actually was only a couple of meters away when she did her walk about. She was in white and red with lots of diamonds and looked suitably regal.
You will have ask Hermes about the Plat Jubilee carre (if there is a scarf - I'm sure there will be). Perhaps your query will prompt H into making them internationally available, I'm sure there's a market.
