On Saturday I picked up a handful of old SF pulp magazines featuring PKD short stories for about $2 each(!) and one of them was the December 1956 edition of Satellite Science Ficton magazine with a cover story by PKD entitled "A Glass Of Darkness".
The story is the first published version the entire novel "The Cosmic Puppets" (about 95 pages).
Anyway, I went online to see if it was worth anything and couldn't find anything (no, not even on Ebay). But I did come across a listing on Amazon.com where someone was selling a used copy for $159. I couldn't believe it.
Turns out that it's probably more realistically priced around $75, but hey, that's still a good bargain.
This Saturday I'll head back to the same seller to pick up a couple more of these pulp SF magazines also featuring PKD short stories.
Woo-hoo!
