There are a few things worth noting here. First, there is a current fad involving the "forking" of the tongue--stupid, but current. Second, the zipper tab is at the wrong end. Third, if you look closely, the brass zipper bits appear to be "painted" onto the tongue.
So, in my opinion, this is not a photoshop job, but a clever make-up job.
Humbly submitted for your cinsideration,
