I can't find an image, and I doubt my dad still has it, but he might do, but I remember as a kid, if we went on holiday to somewhere like Pontins, a portable tv like that would come with us. I don't remember make or model, just that like in that image, the screen was tiny, and it had dials to tune in, but the box was massive
I guess at the time it was amazing, and must have cost an arm and a leg, unless it fell off the back of a lorry?
