You can’t claim monopoly on large vinyl numbers

I write in reference to the letter titled ‘Don’t forget to credit your reference points’ from Morag Myerscough and Ian Cartlidge (DW 16 July).

What incredible egos these designers have. Let’s face it, using large-scale vinyl numbers in Helvetica, or any other typeface, on coloured walls is hardly revolutionary and unique.

I think Myerscough and Cartlidge have missed the point. What makes the Barbican signage (pictured below) exceptional is the fact that the numbers have become part of the fabric of the building – they are superbly integrated 3D sculptures in their own right.

This is a very different approach to that of large vinyl numbers used at the Cardiff Central Library. Get over it.
