I've been avoiding this question because I haven't been quite sure how to answer it. I was born in 1948, and I had a considerably older brother who brought home comics quite often; I also grew up in the Wyoming ranching community, where it was considered a sin to throw away anything that had been printed, the two exceptions being mail order catalogs which were fair game for use in outhoused and newspapers which could be used to start fires after they were a year or two old and it was unlikely that anyone would miss any news they contained. If you had visitors you expected, they would often bring a box of magazines, newspapers, paperbacks and, if they had kids and you had kids, comic books as a gift. When we visited people who knew we were coming we would do the same. Consequently, I was still reading pre-code comics in 1958 but not as many as I had been in 1956. I remembered things I knew were no longer published, and one of my earlier memories has to do with a comic book that was missing pages from the center; I eventually figured out that that book had been 'All-Star Comics' #51, and I must have been bitterly disappointed by the missing pages in late 1954 or early 1955. Let's say that I grew up with an awareness that comic books had been around for quite awhile, and that some things were no longer printed, but my sense of what had gone missing were comics that had featured crime down and dirty crime and horror stories, because I remembered a few of those books and the fact that they upset my mother. However, it wasn't as if I actually had any memories of the "Golden Age of Comics." I recalled parts of the "Atomic Age of Comic Books," but that isn't exactly the same thing.
In fact, I wasn't aware of the "silver age" until I saw the first 'Justice League of America' tryout issue in 'Brave & Bold' #28, and decided something new was going on. My older brother read my copy of that issue and told me about the Justice Society of America, as well as older characters like Submariner, Human Torch, Bulletman, Captain America, Dr. Midnight, Crimebuster, and the Ghost Patrol. A few years later I was excited by the first JLA/JSA crossover. Despite that, the single thing that made me overwhilmingly curious about the Golden Age was when 'Playboy' printed Jules Feiffer's introduction to his "The Great Comic Book Heroes," as a heavily illustrated feature article.
Exposure and interest are two different things, so I'm still not sure how to answer the question which is why I have gone on at such length.
