What a nightmare page: two not-really-core skateboard shops and a subscription advert. I wonder what Middlemore’s thought they were getting into with this BMX advert? Skate Attack in London’s Kentish Town were very serious about rollerskates but I don’t think skateboards were so much their thing.
As to the subscription advert — Like it says:

Clues? Get them here! Neatly packaged and slipped to you in an easily assimilated package of hard-edged action pictures and all-pervading enthusiasm. And the time? It’s getting late: sign up now before the next age is upon us.

We were right about the time. 1989 probably marked another of skateboarding’s peaks in Britain and things did slip a bit downhill after this.
