I've seen alot of discussion on decals and usually they say vinyl is better. But I've never heard if they are time period correct. Did they ever change from one to the other? I've seen what looked like original paint on both cubs and super A's that had a ghost clear backing in indicating they were mylar decals. But am I correct? These were also 1950-55 cubs and SA. So did they change to vinyl later? Was I mistaken and seeing an old repaint job and using incorrect time period decals? Any info on cubs and letter series including supers would be GREAT. TY....
