Recently I got the chance to purchase this hefty sucker and I must say it's an awesome book and it's really well put together. This Omnibus was the one I was most looking forward to next to the FF and X-Men ones so I was incredibly happy to finally own one. I got the Alex Ross cover btw.
Anyway so far I'm up to issue #2 which is a double feature of sorts with one part starring The Vulture and the other half being The Tinkerer and his alien cohorts trying to take over the world. It's incredibly fun and exciting to read as Spider-Man's first adventures in Marvel. I also have a newfound appreciation for Steve Ditko's art which is just really well crafted and stylistically different from Kirby but captures that very same energy in the web swinging and general action.
In fact after seeing the art I see that the people most influenced by Steve's art are David Finch in his rendition of Spider-Man and most definitely Mark Buckingham who's Aunt May and Uncle Ben are almost dead ringers for Steve's versions. The color restoration/re mastering on this is great, very smooth but nothing fancy that alters the art. It's basically re-doing the colors to appear clearer and sharper alongside the line work.
I perused the back for the extras and it has some cool stuff like pictures of the old Marvel bullpen, Steve Ditko original art, unused covers and the actual covers, it even includes all the pin-ups and letters pages.
All in all, this book so far is very much worth the money especially for Spider-Man fans who don't want to spend all that money on the Masterworks or the ones who don't like the black and white essentials.
