Antique Victorian Glass Plate Negative Gentlman Portrait 7x8.5 in

Welcome to my closet 😊 Thank you for visiting! In good condition. I don't know anything about glass negatives or the person in the portrait. The upper left corner shows a corner of my wall art, and I did photograph it in front of a curly light bulb to try to get a better shot of the man. Sorry, but it was the only way I have to show the negative. Please examine photos closely as they are a part of the description.
