When did on ride photos start?

I am 51 years old and have obviously been going to the park for many years. I have been trying to remember when they first started selling on ride photos. Does anybody have any idea or know where I might find out? Thanks

The first that I remember was Magnum XL200 in 1989 (but I was still single-digits). Anyone remember earlier? Hope this helps!

I don't remember any before Magnum. I'm pretty sure that was the first.

Agreed 1989

Thanks
