I recently aquired a few Edison lamp related items from a person whose Great Grandfather worked at the Edison Lamp Company.
I have a bulb, a check , an insert from a newspaper, and origianl photos of Edison lamp works factory.
I attachd images. I am hoping to gain some insight as to what the bulb is? and its age, rarity...any info would be helpful. I ahve more photos but there is a limit as to what I can post.
Thank you!
