Notice the two cards were obviously prepared from the same photograph. That appears to be the only thing they have in common. Each has different publishers, different printers, different wording, and yes, even different clouds in the sky. I wonder which was produced first. My guess goes to the one displaying the copyright. We know the cards were published between 1916-1930 because of the white border on the cards. The change to white borders was made by the US in World War I to save ink.
