I am sorry but I am totally inept at posting pics on GC! I suggest snooping around on Facebook for some... Look for U of Arkansas kids as well as Ole Miss. I know both schools do it.
I did some random googling and found this page

About 13 rows down on this page of pics is a group shot of people where a few are wearing a KKG Loves the Hogs sticker. They are round. Not the best, but maybe some help?
Another thing I would suggest is possible calling one of the houses on campus at Arkansas/Ole Miss and asking who orders these for the sorority. She may be able to put you in touch with their resource.
