The story went for eight issues and led to various spin-offs which explored other areas of the world of 1602 that includes Marvel's superheroes.
I don't think this is Gaiman's best work, Sandman will always hold that place for me, but Marvel 1602 is interesting, though a little too talky at times. Gaiman likes long scripts and this is reflected in this piece. Kubert like his brother Adam (and father Joe) is an amazing artist and has been drawing Marvel heroes for a long time so the art work is outstanding. (Both Kubert brothers now work for DC)
A fun read but you need to know the Marvel Universe to get the most out of it.
