Two offprint issues appeared: one reprinted only the Watson and Crick paper, while the other reprinted the three papers that offered a full explanation of the background to the discovery. For the three-paper offprint issue, the text of the three papers was partially reset, printed as a single column on a small octavo page (unlike the journal issue which appeared in 2 columns), and repaginated  - . The print run of the offprint was small, and it is considerably rarer than the single paper issue. SIGNED COPIES ARE EVEN RARER, WITH ONLY THREE OTHERS SIGNED BY AT LEAST FOUR OF THE AUTHORS APPEARING AT AUCTION SINCE 1975.
This copy is signed in ink by Watson, Crick and Wilkins at the head of the first page, and by R.G. Gosling on the final page, at the end of the third paper, which he co-authored with Rosalind Franklin.
