I have two rules for advertisements. Do something unexpected, and make the reader/viewer feel something. When I was given this assignment I was sent a stock photo of a football sitting on turf with a note, "we were thinking about something like this." BORING! That would blend in nicely with all the other stock photos of footballs that fill the programs. I wanted something that would make the fans flipping through the guide to stop and take a second look. I wanted them to say, "what the heck? What does this have to do with football?" It needed to be something unexpected. And since our target demographic is old enough to remember the moon landings, well... And hey, fun fact, did you know that most of NASA's photos are available with a CC license?
