I'm hoping someone here may be able to help me.

I'm trying to find some information on a book that was left to me by my grandmother. Here is what I do know about the book:

My grandfather was a seaman in the funeral procession of King George V. He was later given a commemorative book. The book is simply titled ‘A Keepsake’ and contains information on Royal lineage, 3 poems (Farewell, A Fateful Day for the Empire and Oft shall We think of Him) and various pictures of King George V and his funeral. It was printed by HW Peall & Co. in London and the only reference to the author is ‘A Memory by One of his Millions. There is an inscription on the first page, which is signed ‘From the Author’. The book is in excellent condition and still in it's original box.

I'm trying for find out who the author was and any other information on it as well as a possible value. I am not a collector and although I treasure it, I have no one to pass it on to and would like to see it in the hands of someone who would appreciate it.

Any information or direction would be greatly appreciated.
