Yeah, it's problematic. There are a few such items on Armageddon that are properly named (Magekiller, Heru's Sword, etc) and ICly famous. None of those have proper name sdescs, buuut (and this is a big but) they are almost all metal which in itself stands out in a world basically devoid of metal. They are also usually distinctly described in some way so that they stand out as out of the normal. I do, however, get that you're going for something a little different here in that players need to be able to produce such things. I also imagine you want a bit of "gee whiz" or "neat" factor for the players as they create nifty looking items that grow in popularity and spread throughout the mud, becoming the latest ingame rage.

Well, the artist always has the option of only producing one of those items to make it a unique masterpiece, but I do get that you're going for something a little different. I think what it comes down to is what's in theme and consistent with the rest of your game world. If a proper named short desc isn't going to stand out like a sore thumb (or maybe the whole point is to have it stand out like a sore thumb), then go for it. If it's going to be jarring and look weird, then choose a different route.

My main concern would be ,mass proliferation of masterpieces and brands in such a system. So, you don't have just Starry Night in a room. Instead you have:

This cozy bedroom is cozily arranged with lots of artwork hanging on the walls:
Starry Night
Guernica
Mona Lisa
The Scream
Sunflowers

And every single person's abode being decorated with "unique" items. Or, if you're looking at mass-produced instead of unique, every single persons' equipment containing, "Crown Jewels."
