DEMAND for pub memorabilia is now so great that there should be considerable interest in the contents of a Dublin city bar being auctioned next Tuesday at Thomas Adams of Blackrock, Co Dublin. As well as the usual advertising signs for Guinness and Gold Flake, the pub material also includes counter presses, corner seats and stools. The Adams sale also covers furniture, such as Victorian extending dining tables, Victorian and Georgian sideboards and gilt overmantles, paintings and some silver.
