This was the main design for the "Rovers" T-shirt in the theme of "Steam Punk".
This was also the theme of the convention.
The final design was printed in greyscale on the back of each Rover staff shirt.
Unlike the first image this design was based on the "Rovers" department. and wasn't used as a shirt design.
Instead it was used as the computer background image on the computer used to check in and out Rovers at Base. There is also a gradient version.
