Hi Marc,
You can just make out the VSTEP logo on the side. It's not very obvious, but it is there.
At the bottom, in the orange bit. And it's on the back too, I'm sure.
It's not uncommon to have publisher names on the cover/box more prominently than a developer's name.
Not the way I would like to see it, as the devs put in all the hard work, but there you have it....
Regards,
Fred
