When John Smith's Magnet Ales were advertised across York

When I was a student in York the corner shops in the backstreets all had advertising John Smith's Magnet Ales.

The shops have mostly closed and, while the name Magnet still survives, the beer is no longer brewed at John Smith's Tadcaster brewery but produced under licence by Cameron's in Hartlepool.

I did find a couple of relics of Magnet advertising when I went hunting for the blue plaque on Frankie Howerd's childhood home in York.
