As a matter of personal preference and as someone that has been casually collecting Platinum Age books since 1985, I make the distinction between books containing original vs. reprint material. I'll only pick up reprints if the cover interests me, but love the all original comics. This was a major leap forward for the medium, at least as significant as the format itself. Early books from what would become DC even promoted this fact, with New Comics 3 bearing the slogan "AOC and how" on the cover and several other issues having it throughout the interior. AOC? All Original Comics. This is what paved the way for the medium to really take off, because there was no issue of paying royalties to the syndicates for reprints. This way, each company paid the artist and the printer and the rest was profit.
