100 years old?

This card also belongs to the “Divided Back” group. That means that it was printed around 1907 to 1915. The picture goes right to the edges and on the back is a dividing line between the address and the message. You can see that people are getting used to the idea that they can write both the address and a message. On the left of the card, the reminder: “This space Can Be Used for a Written Message” has been shortened to “THIS SPACE FOR MESSAGE”.

We are still in Colorado and will be for a very long time. Volume One of my collection focuses exclusively on Colorado. The majority of the cards from Colorado are all about the Royal Gorge. The Royal Gorge is a good 3 hour drive east of Denver. The Arkansas River has carved it out similar to what the Colorado River has done to the Grand Canyon, but on a much smaller scale.

This picture is another picture of the Gorge looking toward Denver. There is a hint in this picture of an amazing engineering feat. You can see to lines at the bottom of the card that seem to go from one side of the canyon to the other. These are the support beams for the, as they like to advertise, “Famous Hanging Bridge”.
This was printed, and it looks like it was also published, by the HH Tammen Company. Because it is a divided back card and there is no mention of any other company and no post marking, the best I can do to guess the age of the card is to say that it was probably printed some time between 1907 and 1915. It is approximately 100 years old.
