I found a fictional brand logo on the net that was about the right size (and one you can't miss)and used that as a starting point. I reasoned that there'd be at least two states for the sign: cleaned and distressed, so I cropped and resized the original to 512x256px and put the clean version at the top and and a distressed version at the bottom, making a 512x512px image. Then I "did stuff" to the bottom version to make it look like it'd been there for a while.
I uploaded this to Seconds, and then applied tit to the backs of seats. The face was set to default with horizontal of1.0 and vertical of .5. The clean had an offset of 0.25 and the distressed of -0.25. And it worked! And then I discovered that the makers of Slum City (the source of the benches) had thought of this years before! Nothing like reinventing the wheel I guess. D'Oh!
