Original vintage 5x7 black and white photograph of: Mount Vernon Terminal Railroad

About 10 years ago, I obtained a collection of train photographs in several 3 ring binders.

These are original vintage prints that could, quite possibly, be one of a kind. 

These might be the only images in existence of these particular trains. 

These are NOT REPRINTS from a home computer. 

These are vintage photos on photo paper taken in the 60's, 70's 80's and 90's.

Thanks for looking.
