These postcards are recent acquisitions. They were published in 1960s when I was a teenager in Rhyl. Card at the top shows (left to right) the boating pool, Coliseum Theatre, paddling pool and then the original Pavilion which was between Water Street and Edward Henry Street.

The other card shows Coliseum, paddling pool, Pavilion, roller skating rink, and then the cycling track which was opposite the Queens. This particular card was not posted; it was part of a batch pushed through a letter box. It says, “Dear Sylvia, we were going to send you these postcards while on holiday but we didn’t stay long enough to write them. Sam & May."
