This is a very early postcard and you
can see it's had some wear, although it was never actually mailed. Written
(probably with a fountain pen) on the back is,
"We can hear this clock strike
all over town & it is lighted at night with electric lights so you can see
to tell the time."
There's no postmark to give away this
card's age, but other clues indicate that it was probably published between 1907
and 1913. According to Mashburn's
The Postcard Price Guide, A Comprehensive Reference, the Divided Back Era was the first time it became possible for both the message
and the address to be written on the back of the card, which left the entire
from of the card available for the image.
