Bryan Kneale (British, B. 1930) "Dinosaur Bones" Original Mixed Media painting on Illustration Board. Provenance: Collection of James A. Helzer (1946-2008), Founder of Unicover Corporation. This artwork was originally published on the Fleetwood First Day Combination Cover for the Great Britain Owen's Dinosauria 1841 stamps issued August 20, 1991. More than one hundred and forty-five million years ago, giants roamed the tropical expanses of a young earth caught in the perpetual summer of the Mesozoic Era. From small, chicken-sized creatures to behemoths weighing more than seventy tons, dinosaurs existed as stalking carnivores or browsing herbivores, and their titanic clashes as predator and prey thundered across the primordial plains. Extinct for eons, dinsoaurs continue to captivate imaginations and stimulate vital scientific research. Image Size: 17.5 x 13 in. Overall Size: 23.75 x 32.75 in. Unframed. (B13217) See More
