The fourth and final deck in the Kings Wild War Time Series is the Invincible - Sherman Tank. The deck inspiration comes from the Sherman Tanks used in WWII by the United States and Western Allies. The specific tank on the tuck case is inspired by the Sherman Tank named the Cobra King. This was the first tank to enter Bastogne to relieve the 101st Airborne Division of the United States Army during the Battle of the Bulge in December 1944.

This series was created with inspiration from USPCC's War Time series that was originally printed in the early 20th century around WWI. Each deck, Old Ironsides, Noble Train, Peter Dash Flash, and now the Invincible - Sherman Tank, all representing different arms of U.S. military might - Air, Land, and Sea.

Printed by the United States Playing Card Company.
