I have a large collection of sci-fi and mystery magazines that are truly vintage, from the 1960s and 1970s. If you have a specific book or magazine you are looking for, let me know and I'll try to see if I have it. In the meantime, here are two magazines that are terrific:
Alfred Hitchock's Mystery Magazine July 1964 volume 9 No. 7 91st Issue. The cover reads: 164 pages of original stories presented by the Master of Suspense. $15
Worlds of Tomorrow, August 1966. Cover by Wenzel which reads: "R.C.W. Ettinger, Victor Borge, Long John Nebel, Frederik Pohl Discuss Immortality Through Freezing Now. Also many new stories and features" $12
