For the 21st Anniversary of the Co-operative Party merit certificates were issued to Women's, Men's or Mixed Guilds. Notice the old style beehive in the left hand corner, they are called a skep and are now illegal in many countries (you have to destroy them to get the honey). The beehive is still used as a co-operative image - it's on the Co-operative Group website, it's an old fashioned white wooden one. Back then it was 5p a year to be a member of the party, and there was clearly encouragement to join if you were in another co-operative members group. Moss Side, and Withington Constituency Manchester & Salford Co-op Parties don't get a mention in the advert though they were in existence and meeting.
