I noticed the other day on Amazon that at least three of the first volumes from Marvel's Omnibus series are getting new printings:
Amazing Spider-Man Omnibus Vol. 1 (August 27, 2013)
The Uncanny X-Men Omnibus Vol. 1 (September 17, 2013)
The Fantastic Four Omnibus Vol. 1 (October 15, 2013)
This is great news for collectors, since these original printings are going for astronomical prices online. Let's hope Marvel releases new printings of more of its initial omnibus titles including the original X-Men, Thor, and others.
I love the concept of the omnibus series, but to tell the truth, they're just too blasted heavy. I own the Fantastic Four Omnibus Vol. 1, but not the second volume, another title that probably costs more from online sellers than your monthly car payment. Instead, I bought the same comics in the Marvel Masterworks series (all at discounts), which all totaled were cheaper than the original omnibus sticker price and are much easier to handle.
I already have the Spider-Man issues in trade paperback, so I won't be getting that omnibus. The X-Men volume is, however, a temptation...
It will be interesting to see if Marvel continues rereleasing these hard-to-find volumes in the coming months....
