Each year Unison highlight their major campaign with 2 large mesh banners which are hung from their HQ opposite Euston Station in NW1 London. The banners are changed every 12 months by C3imaging.

The banners are printed & hung by abseiling teams. Seen from Marylebone Road, one of the main roads in & out of London, they make a very impressive sight.
