The Watson-Crick model of the DNA double helix provided enormous impetus for research in the emerging fields of molecular genetics and biochemistry, and Crick, Watson, and Wilkins were awarded the Nobel Prize in 1962. Ballpoint signatures, “James D. Watson” and “Maurice Wilkins” and a black ink signature “Francis Crick,” on an off-white 5.75 x 4.25 card. Not common to have all three signatures on one item; this is only the second we’ve ever seen. In fine condition. R&R COA.
