Finding Heather's bonus shirts?

[Robbie123]

Hello. I was wondering if anyone knew where I could find the original peice of art design for this shirt for heather.


I'm planning on making a shirt online with it to cosplay in. (uberprints.com, good website.)
oTL; the only art design/texture/whateveryouwannacallit one I've found is this one with robbie on it. It's not mine by the way. I have no idea who made it, I found it on google.

I'm not sure if you can find the original artwork, but you could easily remake it in an image-editing program. All you need is the texture ripped from the PS2 version (I don't have it, but I'm sure someone here can help you) and then just blow it up to the size you want and trace over it.
