This is the limited edition of Regina, issued in 2002 in this particular colourway to mark HM the Queen’s Golden Jubilee (see the text on the purple ribbon at the bottom).
I guess Hermes settled on this particular design to customize / reissue as a special, since she had been pictured earlier that year at a horse show wearing the same scarf in a yellow colourway
Thanks for this contribution I added a new page for this special model.
