One of the better of Warner Brothers' "Big House" films, "San Quentin" stars Pat O'Brien as a reforming guard at the title prison. His new girlfriend, Ann Sheridan, is the sister of one of the inmates, Humphrey Bogart. When Bogart finds out about the relationship he vows revenge. There was a hole with a small amount of loss of paper and a stain in the lower part of the "S" in the title and some pinholes and fold separations. These flaws have been corrected during the professional linen-backing process. Dramatic photos of O'Brien, Bogart and Sheridan in duotone. Fine+ on Linen.
