I can work up a T-Shirt on this theme and give U a link where U can get a few once it's done.
My style is not directly like the Odd Rod guys but it is unique.
To use Ur rod pix as reference requires a note to that effect so there's no prob later - that is if those pix are made by U though no permission is needed for the use of images of the rod in general b/c it is on view in a public place (laws - go figure ~:0) So question is - did U take the pictures?
The Hot Rod in the fotos is fab - I imagine the files posted here are low resolution - it would be helpful to have full rez versions to use for variations on the theme, though for T-Shirt work these low rez pix could suffice ~:0)
What I would want to do - if I go to the effort - is regardless as to whether or not U like the finished product I would still be able to put the design in my portfolio of T-Shirts or derivatives and market my work from the reference pieces.
Let me know what U want to do ~:0) VivaChas!
