The fearsome black silhouette on the Dinosaur Silhouette Visa Gift Card is fearsome enough, until you see the menacing look of its glowing green eye. The Tyrannosaurus-rex was the most awesome predator the world has ever know, standing over 13 feet tall and reaching lengths of 40 feet. Our fascination with T-rex is undoubtedly aided by the fact we don’t have to confront him. Give Dinosaur Silhouette Visa Gift Cards to the dinophiles on your list (hint: kids!).
