Even if you didn't make it to New York Comic Con, you can still view the pristine copy of Action Comics #1 that fetched a record $3.2 million at auction -- every single page of it.
Certified Guaranty Company, which graded the copy 9.0, has a digital version of the entire issue, which contained not only the landmark 13-page story by Jerry Siegel and Joe Shuster that introduced Superman, but also 10 other tales. The debuts of Zatara and Tex Thompson have been overshadowed by the Man of Steel, and the rest of the contents -- "Chuck Dawson," "Sticky-Mitt Stimpson," etc. -- are now little more than footnotes, but they're still of historical interest.
Also, if you want a general idea of what a 76-year-old comic worth $3.2 million actually looks like ... let's face it, this is probably your only chance. The viewer on the CGC website is actually pretty decent, too, allowing you to zoom in to read the text and study the art.
