Guinness in the 1930s was the biggest brewer in the UK and the biggest spender on advertising. In 1971 the Guinness advertising agency S H Benson went into liquidation in London. The art that was produced for clients went missing during the take over. 40 years later in New York, the original canvases painted by John Gilroy for the Guinness campaigns between 1932 to 1960 started to be sold off by a dealer. To date some 500 original and signed oil paintings have been sold for over $5million. This proof artwork is stunning in its range and quality. Not only were the famous zoo animal and Guinness for Strength posters included, but most fascinatingly, hundereds of new posters were discovered. Campaigns and calendars that were never used commercially have been rediscovered. This collection is adverting treasure trove and was not even known to the Guinness archive in Dublin.
