The Ghostsigns Archive has been updated as part of the wider upgrade to the History of Advertising Trust website. There are not only more photos available but also a new search function which allows you to browse just the ghostsigns pages. This is not the main site search but the one pictured above immediately before the main ghostsigns galleries. You can look for brands, locations and photographers as another way of exploring the product and service based structure. Do check out the archive and have a browse of past posts about its origins and evolution.
