This is an approx. 7x9 picture of the double helix DNA strand printed on a sheet of semi-gloss paper. This great picture has been personally signed by the one and only James Watson. Watson is an American molecular biologist, geneticist and zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Francis Crick. Watson, Crick, and Maurice Wilkins were awarded the 1962 Nobel Prize in Physiology or Medicine for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material . Watson signed the bottom right border of this picture with an every letter signature, which is much better than he signs now, James D. Watson. Even rarer, he has drawn a really cool sketch of a strand of DNA. The picture is in great condition with just a thumbnail crease and a very light bend on the bottom right corner (barely even noticeable as scan shows). In addition, this has also been professionally authenticated by 1 of the most respected and trusted companies in the business, approved James Spence Authentication (JSA). Comes with the JSA COA #P77694. The sticker is located on the back of the photo. (Included with the Basic Cert program is a 3 x 5 James Spence Authentication registration card (see scan) printed with a unique certification number corresponding to the alpha-numeric tamper evident label. Each certification number is uploaded into our exclusive database for 24-hour customer verification access. All Basic Cert cards are fully transferable without resubmission.)
