Condition
Fair to Good based on seller description and listing context

Authenticity Assessment
Questionable - several major red flags and previous third-party failures

Semi-legible block-style cursive signature common of period athletes

Large format piece measuring 40.5x27 inches dated circa 1965
Estimated Value
Minimal unless fully authenticated; currently valued near zero or raw poster value due to rejection status
Comparison to Known Examples
Fails to match the smooth, confident apex of genuine Sonny Liston exemplars from the 1960s
Authentication Tips
Compare letter spacing, baseline fluidity, and pressure points against authenticated exemplars certified by major third-party graders
Certification Recommendation
PSA/DNA or JSA (both have already rendered inconclusive or fail opinions)
Red Flags
Explicitly stated by seller that both PSA and JSA were inconclusive or refused authentication, which is a massive red flag for buyers
Provenance Notes
Lacks verifiable chain of custody, relying solely on seller's unverified claims and anecdotal opinions
Historical Context
Liston was one of the most intimidating and dominant heavyweight champions of the golden era of boxing
Market Trends
Sonny Liston memorabilia commands high prices when authenticated, driving a high volume of clever forgeries
Investment Potential
Poor investment due to high risk of non-authenticity and prior rejection by top-tier authenticators
