This looks like a group photo at a “dandy convention”. The convention must be fun because these six gentlemen seem very jolly. The men are dressed identically except for their hats. Four of the men are wearing straw boaters. Note that the fellows are all wearing high collars, cummerbunds, and white shoes. My “dandy convention” theory is just an attempt at humor. More likely, these happy guys comprise a performing group. All but one of the men are young and handsome. The older gent (seated) is smoking a cigarette. If you are unfamiliar with the term “dandy”, here is a definition of the term. A dandy is a man that is inordinately devoted to style and fashion in their appearance and dress.
