@Chase, because the Salween River in Myanmar crossed more than one country, and we know the river we're looking for don't, can't you give @Julie Justice's question a pass? Could use an extra answer point.
I'm at Comic Con this weekend and there has been no Carmen art, merch, or cosplayers that I've been able to find. I suppose it's on-brand to be hard to find, but I had hoped to pick up some swag with the recent upsurge in popularity.))
No merch means either nobody picked it up at the licensing convention or it’s not yet open to third party licensing. On the up side, the cartoon series has won an emmy (juried) for background painting.
