Well, if we were to go all Annie Wilkes, I suppose it would be King himself. Tabitha King already snapped that one up, it being a limited edition and all. In all seriousness, memorabilia is pretty hard to place a value on. I suspect that old typewriter he wrote some of his first books on would probably fetch a princely sum. I suppose it is what the market will bear. I'm a simple guy and since I don't collect the stuff for resale, the monetary value pales besides the sentimental or metaphorical value. Hell, I live in the same town as Sai King and have eaten at the same eateries he is supposed to favor. I guess that means he and I have probably relieved ourselves in the same pot. In the grand scheme of things that means nothing. However, all of us who have read his books have been connected to him in a personal, almost intimate way. That is probably closer and more meaningful than even a day when he signs a book in person and you catch a glimpse. Books are a backstage pass to someone's mind, something they issued the personal invitation for, like being pulled onstage at a Rock Concert. While I love my memorabilia and I'm sure I will collect what I can till the day I die, I still don't value it as much as just another trip between the pages.
