This is a Real Photo Postcard that was tucked into the back of the Nettie Parks Album.
I have darkened the contrast on the back of the postcard. I believe it says: A bunch of E Co boys Guines? ? Cuba 1908
It looks like it was originally 1907 and then someone made the 7 into an 8.
This Real Photo Postcard is a Velox with diamonds in the corners so that indicates that it is from 1907 to 1914.
Thanks for stopping by, do come again:)
Update from Iggy:
When the Cuban president Tomás Estrada Palma was accused of election fraud, he invoked the Platt amendment and requested US intervention. The USA sents in 2,000 Marines and 5,600 Army soldiers (the so-called "Army of Cuban Pacification") to re-occupy the country and military rule extends until late 1908, overseen by Secretary of War, William Taft.
