The Baseball Card Database is site that lets you view every Topps base set card from 1952-2009.
Just enter the year at the top and it will display cards numerically like this:
Then just click on the name of the player and you get a popup that shows you the front of the card along with the card info.
Then just click on the picture and it flips over and shows the back of the card.
I love it.
Somebody put some effort into this and I'm glad they did.
I thought if you had never heard of it you might want to give it a glance.
