Set of four vintage Babycham glasses

A set of four Babycham glasses, with the chamois logo on the glass bowl and the 'Babycham' name around the base of the stem in blue, probably dating from the 1970s.  The glasses were produced as promotional items to serve the sparkling perry drink for the firm of Showerings of Shepton Mallet who invented and produced the product - and it was promoted with the slogan 'I'd love a Babycham'.
