Black & White with UFO

Fleer had a late '80's set with stickers for each team, which featured a stadium photo on the back. It must have been cheaper to use black and white photos of the stadiums. I have a Reds sticker with Riverfront Stadium on the back. Apparently this stadium photo was taken when a UFO was hovering overhead. I thought it might just be the card, but I actually have two of them with the same image.
