X-Men variant cover "No Boys Allowed" shows the new team as young children.

The X-Men comic recently re-launched with an all new premise that fans gave mixed reviews when it was first announced; an all female team! The new X-Men comic is being written by Brian Wood and features a team that consists of Storm, Rogue, Jubilee, Psylocke, Rachel Grey and Kitty Pryde. Artist Skottie Young has created a fun new variant cover for X-Men that features the new team as young kids in a girls only clubhouse titled "No Boys Allowed". The cover is absolutely brilliant and has a feel of Calvin and Hobbes to it.
