The caption from the library reads: "This group is displaying some kind of contraption. The two students are wearing some kind of plastic around the mid-section and the adults are posing for the camera. The only info for this picture is the name 'Tadlock.' The date is 1/18/1950."
Now this is a good three years before I was born, but I suspect this has something to do with the polio epidemic that swept the country in the 1940s and 1950s. Many victims were confined to the infamous "iron lung" machine, and this resembles a portable device used by victims to help with breathing while outside the machine.
Not sure of the names of any of the people in the picture. If you recognize anyone, please
leave a comment here or a message on my Facebook page.
UPDATE: Jimmie Meese Moomaw (author of Southern Fried Child) says the older gentleman on the right is Red Myers, the town fire chief. Thanks, Jimmie!
