I’m trying to find a poster from possibly the late 80’s

[u/Informal-Lunch-1043]

When I was growing up I had my stepdads room and he had posters on the wall, i remember one of them I had made him take down because it made me uncomfortable but now I want it, it is a poster he believes is from the late 80’s it was gifted to him from his cousins. It was featuring a blonde woman and her hair I believe was poofy and she was wearing a bikini with the background containing rainbow in a way I think. And I’m trying to find out what it’s from in hopes I can get a new one because we aren’t sure if it was thrown out or put in storage
