The first variant cover that he did featured "Megatron No More!" and was an Apocalypse Comics Exclusive. It took inspiration from a classic John Romita Spider-Man cover.
Casey has now revealed a second even more exclusive cover set up in the very same manner, but featuring Galvatron as the full body instead of another Megatron picture.
Confused by what I mean?
Check it out below, and see what Casey has to say about the cover here.
Behold... Galvatron! And behold the exclusive print I'll have available at the 2009 London Film and Comic-Con. It is of course a variant of the Apocalypse Comics exclusive cover for All Hail Megatron #12 (and of course it is an homage to the classic cover to the Amazing Spider-Man #50 by legend John Romita).
This print is limited to only 50 copies. I'm also considering only offering it if you also buy Apocalypse's exclusive cover for AHM #12, as I don't want this to take away from Apocalypse's sales. I have a feeling these are going to go fast...
All Hail Megatron #12 was released to comic book retailers last week.
