"One of the first graphic novels" 

The description for one of the pictures on this topic states "one of the first graphic novels".

This is false.  Graphic novels reach back to the Victorian era.  It's neither one of the first graphic novels, nor even one of the first modern era graphic novels, nor even one of he first super hero themed graphic novels.  I can think of no level on which that late 70s graphic novel is in any way a first for the field of graphic novels, aside from being a reltively early one (though not first) for Marvel comics as a publisher.  

I think the best alternative description would be "one of the earlier Marvel comics graphic novels".  That is at least fairly accurate.
