Dave/Howard,

AIS (aka SportsRobe) is the premier manufacturer of jerseys/uniforms to be worn in motion pictures. I have a jersey that is very similar to this one you have referenced -- it is also a gray Seattle Mariners jersey with the AIS tagging -- mine however also comes with a letter of authenticity stating that it was worn in the 1994 film "Little Big League" -- by Ken Griffey Jr. I can check my jersey later tonight to see if it also has a "Russell" patch on the sleeve. I am speculating that because Russell was the official supplier of MLB uniforms, there was a clause in the contract that any jersey featuring a MLB logo at the time must also have a Russell logo on it? (this part is just my guess)
