On looking through some of my books, I came across 'Remember When' by Robert Opie, Iona & Peter's son. He has spent more than thirty years collecting packaging, advertising & social history. In 1984, he opened the Museum of Advertising & Packaging in Gloucester (UK) & in 1999, the Museum of Memories at Wigan (UK). I knew nothing of the Opie's work until this thread got started. What began as 'Pinch,punch' has developed into something much broader & much more interesting. Your thoughtful & insightful contributions are really appreciated, Nigel P.
