Ralph Pallen Coleman - Dodging The Submarines - Gazette Litho 1918

Picked this from a table at a local fleamarket in Delaware.. This is cool wartime print from Supplement to The North American, Co. published in August 4, 1918. The title of the piece is "The Love Story of A Hero-2"
I have been trying to find information on this early print from an original charcoal drawing by Ralph P. Coleman, but have had no luck.. Posting it here because the condition is great.. and it should be shown! A time gone bye when the submarines.. were on everyone's mind! - D.B.
