This could be a hard one to get hold of. Unless you live in Dublin, that is, then you'll be swimming in them.
But Tommy Lee Edwards has created a variant exclusive cover for Spider-Men #5 for Dublin International Comic Expo, held at the on September 29th and 30th. Guests include Tommy Lee Edwards (of course), Kelly Sue DeConnick, John Layman, Matt Fraction, Rafa Albuquerque, Jeff Parker, , Nate Cosby, Tommy Lee Edwards, Ben McCool, Lauren Sankovitch, Mark Doyle, Jeanine Schaefer, Kieron Gillen, Jaimie McKelvie and Doug Braithwaite. It's a fine crowd. Tickets to the show can be bought here.
I've been to the show once, and a very fun time I had there too. I'm jealous of anyone who's going.
