Here they are:  the first twenty-nine issues of The X-Men from way back in 1963-66!

Excellent full color reproduction of the complete stories plus covers (and a few bonuses).

The first eleven issues are all drawn by The King, Jack Kirby! Jack continued to do the layouts for the subsequent handful of issues (one of which was then pencilled by Alex Toth – the only Kirby/Toth collaboration that we know of!), and was then followed by Wener Roth (initially working under the pseudonym, Jay Gavin).

656 pages in all!  Classic Marvel Comics – for less!
