I'm looking for mail-in promos released for the NES. A few different ones I'm looking for are the following but not limited to:

Baby Boomer Cheat Sheet (never seen this one but know it was available)
Faria Map w/ envelope
Dragon Warrior 1 w/ Dragon Warrior 2 Enix Letter

These 3, especially the first, are some biggies that I want to purchase. If anybody has any that they are willing to sell, please let me know! Remember, I want items that were mail-in order ONLY. Thanks!
