I think I might have found a neat reference. Ultima fans, follow me for a moment. Here are screenshots of (some of) bartenders from Privateer. The heads are animated in front of a background that was rendered in 3D Studio.
A larger version of each background is actually stored in the game which gives you a better view. They're for a cut feature so don't ever actually display. But if you look closely there are four different labels for the liquor applied to a variety of different bottle shapes.
But we can get even more detail because the original 3D models and their textures have survived all these years in dev material we've recovered at the CIC!
So Ultima fans: is that last bottle not a map of Britannia?!
