I just purchased a tub of NES games and console and at the bottom of the tub were two Nintendo Power booklets. It's my understanding that these were mail in giveaways. I've attached some photos. I'm looking to find the value of these. I saw only one past sale on eBay but it included the actual envelope they came in.I was wondering what the value would be of these two items as I am looking to sell them. They are in very good shape with no tears and no writing in them. Any help would be appreciated. Thanks.
