The skin of a large eastern diamondback rattlesnake hangs from the side of a barn in this detail from a real photo postcard .

A Vintage Photos Theme Park photo for the theme of a barn, farmhouse, or any variety of agricultural building . This is a real photo postcard of a bank barn with a gambrel roof and roof-ridge ventilators . Next to the barn is a sturdy stone silo . There's no name, address, postmark, or stamp box on the other side to indicate where or when the photo was taken. There is, however, a handwritten note that says, "Skin of a diamond rattler from Florida." I had to take a closer look to spot it, but that's apparently the skin of a large eastern diamondback rattlesnake hanging on the gable-end side of the barn.

A medical photo for the Vintage Photos Theme Park. A real photo postcard published by the Grogan Photo Co., Danville, Ill. Postmarked Chicago, Ill., July 13, 1946. " Iron lungs ," a colloquial term for negative pressure ventilators (these medical devices are no longer called "respirators"), were notably used in the 1940s and 1950s to treat polio patients with paralyzed lungs. Fortunately, with the development of vaccines to prevent polio and the development of new types of ventilators and treatments, iron lungs are now used only infrequently.
