Henry is VERY fortunate. His prices are UNreal, even on small items. He had a Mantle/Maris magazine a couple days ago, that went for like 56.00. I have had two of those in near the same shape for 10-15 over the years. Plus, the photos are NUTS.
But, its GREAT stuff and there are plenty of collectors willing to pay. Plus, he sold an item of mine once for a REALLY NICE price, so thats a good thing too.
