unofficial usc vs ucla rival shirts

I'm trying to locate the shirts that were unofficially made in the late 1990's and 2000's for USC displaying images against their rival UCLA. There were shirts like HE'S GOT THE RIGHT ONE, or MY MAID WENT TO UCLA, etc...I've seen them selling at the football games also outside the coliseum even last year and will probably sell on Saturday at the game also but I'm not sure who's selling them and I want to contact them so I can purchase some shirts from them as well. If you are the ones that creates these shirts or know of someone who is making them, please send me photos of the shirts so that way I know they are the ones I am looking for. Thank you.
