SIR - Does anyone remember a mosaic of Bradford Canal and Cathedral situated in Central House in the 1960s Forster Square Development? If so, I should like to hear from you.

I am the daughter of the artist, a German Jewish refugee called Margret Marks.

I am hoping to publish a book on my mother and I am also trying to locate the mosaic which measured 7ft square. The building was demolished in 2005\6.

If anyone remembers or was involved in the demolition, I would be interested in their memories.
