Yes, this baseball was signed by the man who assassinated Martin Luther King, Jr., and is the only one believed to be in existence. The signature is in near-perfect black ink on the sweet spot. It's a semi-cheapo "Official League" baseball, which kind of makes sense since it would likely be the type smuggled into prison. The ball hails from one of the top political/historical dealer/collectors in the country and is in EX-MT condition. Ray died in prison 30 years into a 90-year sentence for killing the civil rights leader.
