[Books} Analog Science Fact and Fiction 18 Large Format Editions Including Frank Herbert's Dune

Twenty five large-size issues of Analog Science Fact & Fiction were published monthly between March 1963 and March 1965  (28 cm x 21 cm). 
They clearly were not popular as the publication reverted back to the more normal smaller format from April.
On offer here are 18 issues from that period with duplication. 
They include 3 parts of Frank Herbert DUNE series, which were first published in Analog before being reissued in hardback, thus they are the genuine first editions.
