Five collector’s edition versions of the upcoming Serenity Ornament from Dark Horse Comics, signed by Joss with a certificate of authenticity from FOX/Mutant Enemy, have popped up for sale on eBay. There hasn’t been an official announcement concerning these, and they aren’t being solicited by Dark Horse or Diamond Comics Distributors, but the seller told me that the comics collectible retailer she works with offered five of these to auction along with the upcoming regular ones. She was told there were 50 available, although it was unclear if that was 50 total, or just 50 from this retailer.
I have no clue. There’s been no official word, Dark Horse has a deal with Universal, not FOX (as far as I know), Mutant Enemy doesn’t exist anymore, and neither the people at Things From Another World nor Marco at 258 West Authentic (both offering preorders of the ornament) have ever heard of it.
Which doesn’t mean it’s not possible, and it is the sort of attention-getting, cool-stuff-for-the-fans things that Joss might do. Just can’t say for sure.
Updated: the auctions have been pulled, see the comment below from the seller.
