So, this thread was an incredible success. I gave the group three pages of art, one of weapons and two of books. Hooray!
Ironically enough, they were most interested in the block of moldy cheese radiating strong conjuration and evocation magic (nystul's aura, of course.) They're dying to find out what it does.
Here's a sample piece of art they found that I actually came up with on my own:
Massive unfinished sculpture formed of gold, silver, copper and platinum; it appears that coins have been melted in a smelter and poured over dozens of posing victims in an attempt to recreate a battle scene. Their (undead?) muffled screams and groans can still be heard from underneath the hardened and shaped precious metal.
