If they want Golden Age heroes, they should read golden age comics. First, mortgage the house for everything over principle. Then, run down to the comics shop and drop the wad on all the double bagged stuff behind the counter they don't usually drag out for anyone. Don't for the love of God, read any of them. Just leave them in their bags,hang them on the wall in frames and just soak up the golden ageness of it all. There, worth it, wasn't it?
Golden age comics have their place, not in your grubby mitts. They're old, they fall apart, they tear, the staples chew through, the addresses of the ads are outdated.
Just hold your investment and realize, the reason no one reads these and most of these heroes aren't around anymore is; they're boring. They were drawn in an age of different moral standards and attitudes toward violence and sex.( yeah that comics code worked about as good as music industry warnings on albums, lol) Flash was arguably slower, Superman dorkier, Batman had less cool stuff, Capt.Marvel was ambiguously gay, etc.
Give up on this idea, roll a blunt and read a stack of underground comics.
