Think back to your mid teens.

I don’t think I had posters on my walls in my mid-teens. I was just past the ballet dancer stage and hadn't the slightest interest in pop singers.

Adam Ant I thought he was beautiful

Adam Ant really was/ is a beautiful man, but my poster boy was Ian Dury.
(Not that I was allowed posters)

Mick Jagger of course!

Roger Daltrey poster

Here he is.

This one probably. 1964.

Oooo yes, Adam Ant. Lovely pink lipgloss.

My bedroom was covered in pictures cut out of Melody Maker and NME . All different sizes like a jig-saw puzzle with no gaps . I devoured both publications and couldn’t wait for the new one each week, particularly if I had been to a gig the week before and there was a review.

Aubrey Beardsley - The Peacock Skirt

But that is probably not the sort of poster you were asking about. It was a huge poster given to me by my brother.

This is embarrassing. Marc Bolan.

Steve Marriott, Mick Jagger and The Walker Brothers

Marc Bolan is another beautiful man.
I was very in love with him when I was younger than teenaged.

Peter Sarstedt

I wasn’t allowed posters on my wall but if I could have had one it would have been David Cassidy.

Walker brothers and Rolling Stones.

Only allowed one. Gil Favor from Rawhide.

I didn't have any posters on my wall. However, at school we had those old wooden desks with lids that opened. We all had pictures of our heart-throbs sellotaped to the inside of the lid so we could open the lids during boring lessons and gaze at them longingly while pretending to look for a ruler, pencil sharpener etc.

Sorry, OP, I am not prepared to divulge the identity of my pop singer, the family cannot believe it! And neither can I for that matter

Same as Grandma70s, no posters - or interest. I read a lot of science fiction at that age.

Marilyn Monroe on a pink background, and the free poster from Wings' album, Venus and Mars.

Oh, I’d forgotten The Yardbirds. Keith Relf. But my true love was Billy Fury.

Posters were banned in my Bedroom Too, but I did have quite a bit of my own Artwork up and Declared it 'Homework' from my A Level Art Class. Quite a bit of it was inspired by David Bowie or Pink Floyd, Outerspace, Volcanoes and Glaziers. My main Heart throb was a real life one who I adored, and would have Married in a Heartbeat if Circumstances had have been right, he believed that I was too young and needed to spread my wings further before settling down, so I married someone else, but it did not last.
Meanwhile, my Heart Throb was tragically killed in a Road Accident, aged just 26.
I still feel a bond with him even today, and after 34 years with my DH2, who's own DS from his first Marriage shares the same Christian names as my Heart Throb from my younger years had.
