Ha! The expression a million middle age men make in a mirror! Tough guy!

It seems he was the managing director of the People's Institute in New Your City. Here is a book he wrote: books.google.com/books?hl=en&id=xZcXAAAAYAAJ&dq=C...

Charles Sprague Smith (1853-1910?) founded the People's Institute of New York City in 1897. The Institute presented public forums on current issues, and the consequent "forum movement" it inspired eventually expanded to more than 100 locations, mostly in the northeastern United States. Later, the Institute was also involved in opening social centers, usually at public schools, and it organized a school for community workers. The People's Institute closed in 1934. Smith had been a professor at Columbia University, and was the author of several books, including a 1908 volume of poetry. For a Progressive activist, his verse was remarkably old fashioned. In addition to the book of poetry and the book linked by cecilacase above, his 1903 volume on four Barbizon school painters is available from Google Books, as is his anthologized essay on the Spanish legend of El Cid.

Looks like he's fixin' to whoop somebody's butt!

I'm Charles Sprague Smith, and these are my nipples.

William Sulzer (1863-1941), governor of New York, briefly--he was impeached before he'd even served a year: en.wikipedia.org/wiki/William_Sulzer Might also be his brother Charles August Sulzer, who was also in politics, if the men had similar faces?

pennylrichardsca and Wystan: Thanks! We'll add Sulzer's full name and the date to the description next time we update.

A repeat appearance: Amos Richards Eno Pinchot (December 6, 1873 – February 18, 1944) was an American reformist. He never held public office but managed to exert considerable influence in reformist circles and did much to keep progressive ideas alive in the 1920s.

Amos and his his older brother Gifford Pinchot, who were very wealthy, were major supporters of Theodore Roosevelt's run for the presidency in 1912 and contributed substantial funds to the unsuccessful campaign.
