As of this moment... the X-Men no longer exist as a team!
Roy Thomas left the X-Men in 1968. He'd be back in less than a year.
It's safe to say that his immediate successor, Gary Friedrich, was probably only a fill-in. Thomas plotted the first arc, which was concluded in a crossover with his own title, Avengers. Friedrich only wrote one of his four issues independently. #47 was co-written with Arnold Drake, who then took over for the remaining six issues until Thomas's return. Stan Lee was still credited first.
The art team for the eleven issues was more consistent. Issues 44-49, and 52, were all laid out by Don Heck and penciled by Werner Roth. 50-51 were done by the famous Jim Steranko, 53 by Barry Smith (who would later, as Barry Windsor-Smith, do some unforgettable work on Thomas's Conan the Barbarian title I mentioned last time) and 54 by Don Heck by his lonesome. Iceman's and Beast's respective origin arcs in the back-ups of issues 43-46 and 51-53 were drawn by George Tuska and Werner Roth respectively.
