The various alchemy recipes in the game don't use the same world and inventory art. I'm not totally sure that this is a bug, but some of the choices used (like the sealed letter art) are kind of bizarre.
I'll list all of them below for comparison, in case you guys think the inconsistencies should be corrected.

Something I happened to notice is that all Atronach Forge recipes and all Spider Crafting recipes (DB) use "Clutter\Books\Note02.nif" for their world art and "HighPolyNote02" for their inventory art. This doesn't necessarily mean that the alchemy recipes were supposed to use that combination, but it would probably make more sense.
