I'd definitely grab one of the discount hats on the table and then try to work my way over to the hat shelf on the far right. I can't quite make out the price of the hats on the table as that ghost lady is in the way.
I have the Ken Burns Civil War tele series stuck in my mind. And Aldershot lectures on your nation's famous battles and I believe this scene is of the Maine regiment veterans under Chamberlain. Do give a look then report back please.
The photo, I believe taken Gettysburg reunion, where the veterans blue and gray ran up to meet.
A movie reel captured circa 1913 with voice and a Union man remarked the 'rebel yell.'
I went to google my recollect and found 'Gettysburg 50th reunion' with the pix but the ran caption read taken at Cemetery Ridge.
These men were rebel infantry in Pickett's command. Union veterans took positions placed Seminary Ridge. I thought for sure the pix were Chamberlain's men.
My British Army American Civil War cadet study gave strong place to Antietam and Gettysburg.
