Metal Pepsi sign

I found this metal Pepsi sign when I rode over it on my bike in the woods sometime around 1980! I dug it out of the ground, took it home and cleaned it up. Later, my Father and I built the wooden frame. Based on what I've read, I believe it dates to the mid 30's. The sign is in very good shape except for the extreme edges. It is about 22" x 40". It seems difficult to tell what this might be worth but my wife and I love it hanging on our wall! Any additional information would be appreciated.
