This lot of 21 postcards are mostly real picture postcards. None of them have been written on, stamped or posted in the mail. They depict the natural disaster of 1937 in Louisville, Kentucky when the Ohio River flooded. I took a picture of each postcard so you can see what is shown & how the corners look. They are in good condition overall. There are many businesses that are identifiable, as well as many of the major streets in the downtown Louisville area. Very cool collection of history on these cards. There are 2 different backs in this lot as you can see in the pictures.
