Uniform's with sponsors listed

[DaveASA/FED]

I know this is more a code question than a rules question but was just wondering if anyone had heard the answer. I was asked by a local graphics shop owner if there is any limitation of amount or size of sponsor logo, or name that can be on the uniforms of an all star team. I know at least in FED there is a limit to uniform manufacturer can only be X tall and Y wide etc. and ASA has the no other organizations logo or name can be on there. But I have never seen anywhere dealing with a team sponsor. Again, I know this is more of a code issue but just wondering if anyone had the answer.

Thanks
