This small metal sign was near the King Edward billboard along I-20 in Edwards I wrote about the other day. It reads, "Hep Prevent Forest Fires" and also includes the words and logo of the Mississippi Industrial Land and Timber Corporation. I doubt it any traveler could have read the sign since it was so far off the interstate, so maybe deer, possums, raccoons and squirrels were smarter back then than they are today.
I couldn't find much information about the company other than that it was formed in the early 1960s and dissolved in either 1971 or 1989, according to corporate records kept by the state of Mississippi. If anyone knows anymore, post it here!
