1907 Mellon National Bank of Pittsburgh Antique Cabinet Photo Panic of 1907

This is yet another fine Antique photograph showing two possible Pittsburgh business proprietors in the year 1907.  We know the year as the calendar states such hanging on the wall. And we know this office has a newfangled telephone as well.   One can see the hands of a secretary at her desk and what appears to be a stack of money.
 
The calendar is from the Mellon National Bank in the year of 1907 as mentioned which was the year of the national bank panic.
 
The Bank Panic of 1907 occurred during a six-week stretch, starting in October 1907. The trigger was bankruptcy of two minor brokerage firms. A failed attempt by F. Augustus Heinze and Charles Morse to buy up shares of a copper mining firm resulted in a run on banks associated with them.
 
Back to the telephone by 1907, AT&T had a near monopoly on phone and telegraph service. In the background is a poster for a Sportsman Show.

 
Now for the two gentleman pictured in the photograph, One wears bib overalls with a shirt and bow-tie and the other in a classic derby hat with a black suit and Nauru shirt.  No identifications on the verso of who these gentlemen are and why they were photographed?
 
But they certainly look they belong there.
