This is a black and white image featuring a grid of six portraits, arranged in two columns and three rows. Each portrait is labeled with a name and the word 'Before' or 'After'. **Top Row:** * **Left:** A portrait of Frederick A. Cook labeled 'Before'. He has a neatly trimmed beard and mustache, and his hair is short and styled. He is wearing a suit with a high collar. * **Right:** A portrait of Frederick A. Cook labeled 'After'. He has a long, unkempt beard and long hair. His face appears weathered and gaunt. **Middle Row:** * **Left:** A portrait of Roald Amundsen labeled 'Before'. He has a mustache and neatly combed hair. He is wearing a suit with a waistcoat. * **Right:** A portrait of Roald Amundsen labeled 'After'. He has a more rugged appearance with a thicker mustache and a weathered face. His hair is slightly disheveled. **Bottom Row:** * **Left:** A portrait of Emile Racovitza labeled 'Before'. He has a long, pointed mustache and neatly combed hair. He is wearing a suit with a waistcoat. * **Right:** A portrait of Emile Racovitza labeled 'After'. He has a more unkempt appearance with a thinner mustache and disheveled hair. His face appears more weathered. Below the portraits is a caption that reads: '(We were all reasonably good-looking when we embarked, but we were otherwise when we returned. The long voyage effected a radical transformation in our physiognomies.)' The overall impression is that the portraits document the physical changes experienced by these men during a long and arduous journey, likely an expedition to a harsh environment.
