This 1930’s poster depicting the Northern Ireland beauty spot Dunluce Castle in Co Antrim was the top lot at the James Adam sale of the John Rogers Vintage Poster Collection in Dublin this week. Designed by Julius Olsson it tripled its estimate to sell for €3,200. Five bidders competed and executed a total of twenty two bids before the hammer came down. The online auction was 96% sold and made €103,000, which exceeded the top estimate. One unusual result was that on average each purchaser bought three lots.
