Vibranium first appeared in Daredevil #13 (February 1966), which was written by Stan Lee and illustrated by John Romita. The variation first introduced in Daredevil #13 eventually became known as Anti-Metal. This variation's unique attribute is that it can cut through any metal known to man. Later in Fantastic Four #53 (August 1966), by Stan Lee and Jack Kirby, a new variation of vibranium was introduced in the isolated nation of Wakanda. This variation had the unique attribute of being able to absorb sound. This is the variation which is most often identified in continuity as simply "vibranium".
This piece is based on a real life cat. He likes to stroll around my house, making himself at home on the porch on the deck and sometimes even in the the flower bed right atop the flowers.
