This ad appeared in 1902 in the Publishers’ Weekly. I have not seen two different editions of this book. Although the advertisement notes the second edition now ready, I suspect that there is no distinguishing feature between the different editions of this book.
It obviously was a big seller for Altemus since it went through at least two editions within the first year of publication.
