nice scarf! (i am currently waiting for one to arrive on my doorstep to take an up-close & personal peek.

)
... but as far as proceeds from scarf-sales go (towards
panthera, the organization) - i believe your SA is mistaken. as far as i know, that is only true re: the panthera pardus design.
with regards to all other items sold around the exhibition (see doloresmia's link), the information is somewhat muddled as to what sales/proceeds (and to what percentage) actually go towards panthera. (at least i can't find anything definitive and am still waiting to hear back from hermès on that very topic.)
quote from the article: "[Kaplan] cuts to the chase: “What Hermès is doing is giving us access to one of the most impressive clientele lists; that’s an act of utmost generosity.”"
hm... okay... i also understand that the admission is free but what about money made from the merchandise?
does anybody have more conclusive info re: this topic?
