Long version: There is a whole bunch of styles going on there. The textured fill around the central illustration has that geometric Art Deco feel, but is ornate enough for Art Nouveau. Yet the illustration of the narwhal and the ship is very representational, not the flat/abstracted style of Deco. The containing shapes and the typeface for "Imperial Stout" suggest late 19th/early 20th century financial documents, while the Narwhal wordmark has an almost "wild west" thing going on. Short version: That's another great looking label for Sierra Nevada, and I can't wait to try this beer.
