There are little postings on the walls in the HOF reminding people of the major rules of baseball; including not betting on baseball. Also, there is only one mention of Pete Rose's 4256 hits in the hall and thats in the All-Time room where all the major stat's are located.
His Jersey and memorabilia does not mention his accomplishments in the least. He's a pretty cool guy, cocky, but I think most professional athletes are in some fashion.
