Never know what you may find digging through my stash. While looking for something else I found this letter I kinda forgot about. I have talked about the incredible Polk's warehouse dig here before. Here is the letter I wrote to "get in" Very few were allowed entrance, only if Nat liked you. Pretty cool in the fact that's it's signed by Nat himself, a pioneer in the slot industry with his brother.
Notice the line about charging 1967 prices. I struck a kind of friendship with Nat and he only charged me 30% of the original prices! He told me he bought everything for 10 cents on the dollar when the fad crashed in'67.
