This is one of my favorite items that I have found. I found it an old abandoned house when I was a teen, about 1977. The house was falling in and I was exploring, like I shouldn't have been . Anyway, it's a post card from the Bentonville Weather Bureau dated November 28, 1924. They evidently sent post cards out to whomever requested it, giving the weather forecast for a day or two at a time. As you may or may not know, Bentonville was the smallest town in the United States to have a First Order Weather Bureau. It was provided through the help of native son and US Senator James H. Berry, and was a testament to the huge impact the Benton County apple market had on the United States as a whole. It was in operation until 1942 and was located on the northeast corner of NE 2nd and A.
To my knowledge, this post card is the only one like it still in existence, as they were normally thrown away nearly as soon as they were received.
