As promised, here's the other pic of Lindens & Newlands I was talking about. It was taken from slightly further down Claremount Road and probably about 15 years earlier, before many of the buildings down that end of Wallasey Road had been built, some of which can be seen in the postcard view.
What a great pic. You've convinced me! Thanks for all the posts, this has been a really interesting topic. I'll have to see what else ebay has to offer!
