Original modern artwork poster from England, 1982

Vintage eighties original print, purchased in London in 1982. It’s called “Cathy’s Kisses”, signed “Wise 82” or “Nise 82”. Hard to tell from the writing. Print no. 9/10. It has a small 2-3” tear at top left side, which can be easily repaired. Will be shipped rolled up into a poster tube. Super cool retro piece of art. Might be worth something, but to be honest I haven’t done much research into it. It doesn’t suit my style anymore, so I’m parting with it Marie Kondo style.
