I knew Frank Buckles and wish I knew him longer. He was kind enough to allow me to interview him on seven occasions, and for that I'm deeply grateful.
My son even got to meet him on two occasions. I received a note from him written by his daughter Susannah just a week before he passed away. I understand and support the capitalist system, but would ask in this special case perhaps people, historians, authors, etc., could refrain from profiteering, unless profits go to Susannah.
I believe that's how Frank would have wanted it.
