Walker did not have any picture after his carrer!
I found few of them one in 50s and one was was from 60s.Walker didn't like to be pictured?
He had so many pics from his pro bouts and personal life 1920s/30s but after that there are very few of his pics.

 

Ok search Mickey Walker and what you got douchebag?
Only pics from 30/40s!
There is one with Archie Moore-1955 and one with Dempsey 1964
