Q: I have attached a photo of a book – Allegories of the Heart – that was presented to my Grandfather in 1903. Can you tell me the approximate publication date?
A: This book is part of the Vademecum Series. It was published in 1902.
See http://henryaltemus.com/series/series180.htm
This series of reprints generally changed covers every year or two. During 1902 there were a number of different possible cover colors. In addition there were more than forty paintings seen within the front cover design.
