Per Blake Bell, Marvel Masterworks Amazing Spider-Man TP Vol 1 features the original artwork from Amazing Fantasy #15 that is currently located at the Library of Congress. It also features a commentary on the artwork that he wrote.

Today, Marvel Comics is releasing a paperback version ($24.99) of the Marvel Masterworks that collects up to issue #10 of the Ditko/Lee Amazing Spider-Man run, but what makes this printing so special is the main bonus feature.

For the first time ever, the original art of the origin story of Spider-Man (from Amazing Fantasy #15, Aug '62) that was donated to the Library of Congress last year will see print in this volume.

Also, Marvel asked me to contribute not only a two-page essay on the discovery, but to provide commentary on each of the 11 pages in the story regarding what I saw of interest on the original art. I was given access to seriously high quality and super-large scans of the artwork and found some fascinating stuff that will only add to the legend of Ditko and Lee's creation and the process behind developing the work!
