A reminder of something written in the posting instructions for this thread. If your post is unanswered this is probably the reason.
It is also the preference of the authenticators to comment on current, not closed, auctions and sales, and to give authentication to members who post in a range of threads, not just requesting free authentication for designer items. If your request is not answered here, for whatever reasons, professional authentication services are available outside of PF.
Reposting this for those who appear to have missed it.
