Does anyone remember this TV show?

Young boy had a cardboard box which he charged people to look into.

Maybe called Penny for the Peepshow or similar?

If so, what was in the box? My mum switched the show off so I never found out.

I think it may be Pin for the peepshow

From a review on imdb

The title A Pin to See the Peepshow came from a scene at the very beginning of the first episode. A little schoolboy had made a peepshow in a box. An older girl came up to him and asked him if she could have a look and he said 'You have to give me a pin first'. She was irritated by this but took a pin from her clothing and gave it to him. The view inside the peepshow was beautiful: white and shining with snowflakes and cotton wool. This older girl would be captivated by the little boy again in later life as he would become the lover who murdered her husband.

And that's as close as you'll ever get.
Cue Brad Pitt "What's in the box??!!"

You'll have to imagine some kind of Narnia inside.
I've looked for you but there's no clips, footage or rental of this anywhere that I can find as it's from 1973 so over fifty years old.

I always find it sad, so many old films and series out there, that no one will ever get to see.

For anyone who was curious about such things' existence!

There's always someone on MN who knows. Love your work, @TheIcecreamManCometh !

Thank you for the description. I'll never see it but can imagine.

I wonder why my mum was so outraged that she turned it off? I assumed it had something sexual going on.

I know! MN is fantastic for this. Much appreciated ❤️

You're welcome. I'm a geek so found it interesting.
Presumably your Mum detected a frisson!
Or perhaps she realised it was going to become True Crime and escalate quickly!
