I have always loved how Jack Barry wrote:
"I wish I looked like this picture now" for Doc Steen on his M101-2.
Barry was 23 on February 23, 1911, when this supplement was issued. He was probably about 53 when he signed this for Steen, approximately 30 years later. And he lived to be 3 days shy of his 74th birthday (on April 23, 1961).
