Cool site for all the pre war/T sets?
 

Is there an online resource for all of the sets pre war? Describing each set, origin, samples, ect...

Have you tried oldcardboard.com, great site

that is a great site thank you!

Any others? Anything with history/essays and such?

Old cardboard is definitely top drawer.
I also find myself turning to Net54 member Frank Ward's site frequently---
fkw cards. He's done a great job dealing with scores and scores of vintage cards.
all the best,
