Including a few very old stories; works that inspired many stories later on and created by authors who were pioneers and main exponents in certain genres. Passing through the 70s/80s and coming till 90s old-style manga. In those past decades, I think many great series were released and, to be honest, I often find myself enjoying these stories more than the recent ones. That art, that vibe... ahhh I simply love reading old manga!
