I got a replica Nalathni Dragon from Dragon Con Swag and Seek!
For the unaware, there is a thing people do at Dragon Con (and possibly other conventions) called Swag and Seek where people make trinkets and leave them around the convention for people to take. This is probably the coolest one I found this year.
I have no other details because the gimmick with swag and seek is that you just leave little goodies around the convention area. But it's definitely not an official WotC thing, that's a safe assumption. I have no idea what Brothers Wilmot is, I haven't visited their site. Generally the swag you find isn't an advertisement like this is, though some people still do it.
