Big Jim was huge in the 1970’s till early 1980’s - finally a more sophisticated doll for the guys. An action hero - not just a military figure (toy soldiers had been around forever). Big Jim and his ‘offsprings’ could do amazing stuff - like there karate chops when you pressed the button on his back and the bulging biceps.
Today Big Jim seems completely forgotten and compared to todays superpowered robots and combat creatures he looks almost like a pacifist.
