RARE LARGE VINTAGE 8 X 10 GLASS PHOTO ENGRAVING NEGATIVE EARLY 1900S FACTORY

Early 1900s large format 8 x 10 glass negative of early engraving showing the National Engineering Corporation factory, South Lowell, Massachusetts. This is an original negative, one of a kind, produced around 1915. It would have been used for producing company catalogs, posters, annual reports, etc. It is in very good condition, with black paper backing. The paper backing may be flaking due to age, but the image itself is in excellent condition.

Thanks for looking. I have several of these, and will be listing more shortly.
