Q: I have a copy of A Wonder Book Hawthorn small with no publishing or copyright dates. Can you tell me how old it is and if there is any value to it other then its cool!
A: Your book is part of the Petit Trianon Series and was published in 1903-1904. During this year all the Petit Trianon Books had the same pedestal design on the left of the front cover (white, pink and blue have all been seen). On the right half of the cover one of 16 flower pictures were possible. For all the possibilities see http://henryaltemus.com/series/series143.htm
This book only has nominal value.
