The discussion in one of the other threads concerning a book treasure brought to mind this book “The Album of Autographs of Representative Railroad Men of the United States”.
There’s no preface, no explanatory text concerning the why and wherefore of the reason for the book and no after word. The signatures are in random order and run the gamut from just a signature to a signature along with a bit of personal information such as residence, railroad of current employment, current occupation, etc. The signature style would suggest the book was compiled in either the late 19th Century or early 20th.
The first 30 pages are an alphabetical index of the signatures listing the name and the page on which the signature can be found.
In alphabetical order the first and last names are Ackert, L.H. and Zugen, Henry H. In case you are wondering Ackert indicated he worked for the EJ&E and Mr. Zugen worked for the CNJ.
This is the most unusual book of railroad history I have seen.
