Thanks Adam - yes, both were part of an OO collection sold by Jim Payette years ago. I happened to phone him one day and asked if he had a Dark Mysteries #19 and he said, "Yes, I'm looking at one right now." I said, "What grade is it?" And he replied, "looks about near mint." I asked how much he wanted for it, but out of consideration for you and others I wont say how cheaply I got it.
I then proceeded to ask, "Venus #19? Chilling Tales #16? Tormented #1? Menace #4?"
Plus a couple of others I had at the top of my wants list at the time. He had them all. I was very poor at the time, or I'd have asked about other books.
The Chilling Tales and the Tormented are still with me, the others long gone, and the pair are currently being graded. I don't think they will do quite as well, but we will see!
