There was a visit to the city by The Queen and Duke on 3rd November 1955, and they visited Cadbury's at Bournville, King Edwards School, Lucas's Great Hampton Street and opened new colleges of Technology, Commerce and Art at Gosta Green, there's a couple of photo's in Alton Douglas's Birmingham in the Fifties Vol 1.
My memory of the visit, the school went to The Pavilion Picture House at Stirchley, saw a film of the Coronation and then travelled to Bournville, where we stood to watch them drive past, I seem to remember having a small tin box containing chocolate.
The Queen Mother visited Kynoch's, Witton and H. Samuel Ltd., Hunters Road, Hockley on 2nd May 1957.
The Queen and the DOE also visited the Scouts' Jubilee Jamboree at Sutton Park, on 3rd August 1957.
