All four old photographs of the same content are laid out side by side, each of diering brightness, on the surface of a deep blue background. In the photograph, mid-aged men, all dressed in long-sleeved shirts lined up in front of an honorific arch, posing for a group portrait. On the arch, there hangs a banner that reads: thesorrowsand joys of middleage. This is a photograph I have found by chance. The era to which the characters in the photograph belong to can hardly be determined. What is definite is only the mid-aged men and the characters in the banner.
