[HOF Auto Rookies]

Was just wondering (and I know this is a huge topic for debate, and I'm sorry), when do you guys consider the first baseball game ever played is? I know some dates to consider are June 19th 1846, October 6th 1845, and uniforms first used and an outside squad I believe on June 3rd 1851.

And anyone know the rosters?

I am wanting to know, because I think it would be neat to try to compile autographs of the originating members, so if anyone has knowledge on this and who has known examples of autographs as well, that'd be great!

Thanks
