*1941! Scrawny would be soldier Steve Rogers tried to sign up for military service, but was promptly pronounced 4F - physically unfit to serve! Dejected, he headed for the door...just as opportunity knocked! Army scientists accepted the spindly specimen for an especially secret experiment! After ingesting the Super-Soldier Serum, Rogers's bony body was bombarded with bizarre "Vita-Rays," and his formally minuscule muscles began to bulge with brawny might! This miraculous metamorphosis, combined with rigorous training and an inborn courageousness, have made this ageless Avenger the ultimate freedom fighter - Captain America! *Source: Back of Card
