The artwork is a United States patent for a mobile launching system, filed by Charles A. Johnstone on April 19, 1957, and granted on May 16, 1961. The patent describes a system for launching projectiles from a ship, using a novel design that allows the projectiles to be launched in any direction. The system consists of a series of tubes that are mounted on the ship's deck, each of which is loaded with a projectile. The tubes are then fired in sequence, using a complex system of gears and levers. The patent also includes detailed instructions for operating the system.
