Finally, I was also able to be one of the lucky 40 people to put my hands on this A3 gyclée print signed by Kevin O'Neill, and produced in February 2014.
This gyclée print has been advertised here, and this is its official description:
This high-quality giclée print is A3 (297mm x 420mm) in size and printed on thick, 300gsm Aquarelle rag paper. The image is taken from a splash page in the book which we loved so much that we decided to offer this print up to accompany it! There are just 40 copies up for grabs so we’re limiting it to just one print per person.
In November 2014, another favorite of mine, Marshal Law, was offered the gyclée print treatment. It is limited to 50 signed copies (Kevin O'Neill and Pat Mills), and is described as this: The un-cropped artwork has been giclee printed onto a wonderfully thick and textured paper-stock (310 gsm).
