The final card of the week is a colored photo of Lake Michigan from Mackinac Island, MI.
Genuine Curteich-Chicago “C.T. Art Colortone”
It’s not clear what is happening on the lake, but the safe guess is that there is a small steamship in the middle distance. The card has several bits of damage, including the folded lower right corner, and some very subtle mechanical cancellation in the upper center.
While it is impossible to date the photo from the picture itself, the card was mailed and has a postmark of July, 1929.
