Here is a nice postcard from Ann Hayes: this one shows The Cross (High Street at the junctions of Wellington Road and Russell Road).

Ann says, “I love this card as it’s the Rhyl I remember as a child. I well recall seeing the policeman directing traffic in the middle of the road. He'd soon be run down nowadays.”
I like this card too, but it is not easy to date. Must be older than 1950s otherwise the shop name Talbots would be on the blinds to the right of the picture (instead of 'music' and 'sports' as above). Doesn’t look old enough to be pre-World War Two, so let’s say 1940s.
