The Vigilant - what is there to collect?

I'm just trying to work out what collectable items are out there relating to The Vigilant - so far I've found

a). the 'normal' issue of the comic

b). The Forbidden Planet exclusive cover (here signed by Simon Furman [on the left] and Trevor Hairsine [on the right])

c). A poster, signed by Simon Furman again, that was available at a recent con. in London

d). A poster, signed by Simon Furman again, that advertises the launch date

If you've spotted anything else - please let me know
