The poster is a PDF file which contains a vectorized image. You can use it for big posters related to Charles Darwin.
PRINTER TROUBLE: I found out that the image cannot be reliably printed on a big network printer under MS-Windows. (My cheap inkjet network printer at home driven by a PC with Linux performs well.) In case of trouble you may try http://www.snrk.de/BeagleLaidAshoreSnarked.svg.7z or a high resolution pixel graph as an alternative.
The print is based on a drawing by Conrad Martens, etching published in: Francis Darwin, Life and Letters of Charles Darwin, p. 160, 1888. Conrad Martens’ drawing has been engraved by Thomas Landseer and published in the year 1838 by H. Colburn in The Narrative of the Surveying Voyages of HMS Adventure and Beagle.
This image actually is an assemblage: I took the liberty to add two persons (drawn by Henry Holiday and cut by Joseph Swain in Lewis Carroll’s The Hunting of the Snark) to the image. But I didn’t touch the vessel. Frame the image and give it to friends and family. You don’t necessarily have to tell them about the little easter egg in Conrad Martens and Thomas Landseer’s artwork.
