[nuclearblues]

two options:
a horrible weapon, the proliferation of which have led to severe consequences on the political interactions of nation-states have been disastrous and unequivocally changed the very nature of human existence;

or preferably, blues music from the cold war period. absolutely wonderful music, though that may have a bit of a limited scale when it comes to trying to properly maintain a store :P

[CrypticEyes]

A bunch of necklaces with eyes on them, covered in cryptic unknown languages. All of them are gold, with the language being overlaid in a green-emerald like stone, that you're not quite certain of what it actually is...not quite emerald, in fact it's something you've never seen before, but rings familiar in a small facet of your mind.
