Has anyone else ever seen this ad?

I recently bought this two page magazine ad off a well known auction site. I thought I had all of the 1978-79 advertising and then this came along! I’ve never seen it before, maybe someone else has?

Of the centerfolds I've seen in my life  that's one I would hold on to

I’m going to frame it to add to my display! And when not displaying I’m going to hang it in my bedroom. Okay, the second part definitely won’t happen. My wife would kill me. Although I may do it just to see the reaction 😜😂
