Unbound Calder Naked Lunch Signatures (1964)

London, England: John Calder (book, primary, rare), 1964.
8.25" x 5.375" x 1", 252 pages in sixteen mostly uncut signatures.

Rare unbound signatures for the John Calder edition of William S. Burroughs' The Naked Lunch, published in 1964. This set is the full sixteen signatures of the bound version, and clearly have never been bound into boards.  It is not known how many unbound copies made their way to the collecting public, but likely very few.

The only other set that I am aware of is in the collection of Bradley P. Allen.

Not noted inM&M, Shoaf, or Schottlaender (v4, v5).
