I guess that technically one of these is a magazine, but it looks and feel just like a paperback.
Brunner, John. The Traveler in Black. Ace, 1971. First edition paperback original (no statement of printing and 75ยข as per Currey), a Fine- copy with slight wear at points and a drop of discoloration to bottom page block at heel, otherwise a very nice copy. Celebrated fix-up of linked stories. Currey, page 74. De Bolt, The Happening Worlds of John Brunner, page 57.

Moorcock, Michael, editor (John Brunner, Roger Zelazny, J. G. Ballard, etc.). New Worlds March 1966, Vol. 49, No. 160. Compact SF, 1966. First edition magazine in the form of a paperback original, a Near Fine copy with slight glue ridging to spine, slight wear at points, a faint, thin line of abrasion down rear cover near outer edge, and a few touches of general wear. Right in the middle of Moorcock’s acclaimed run as editor of New Worlds when it became the epicenter of the New Wave, with a murder’s row of writers in this issue. The Zelazny is the first appearance of the classic “For a Breath I Tarry” (Levack, Stories 69a), and both this and the above came from the last purchase of books from Bob Pylant’s Zelazny collection.
I have cover scans, but for some reason BlueHost isn’t letting me upload pics right now, so you’ll have to wait to see them…
