Worcestershire auction house Kingham & Orme – shortly to be renamed Kinghams – will conduct the sale on April 17.
The auction marks the half century since Dennis held his first selling exhibition (of Doulton art pottery) at his Kensington Church Street galleries – an event mentioned on the front page of the first-ever Antiques Trade Gazette.
The sale, which includes an illustrated talk from the man himself, includes objects of the kind Dennis championed, many from the once neglected field of 19th and 20th century British art pottery. As a leading dealer, scholar and publisher, Dennis helped revive interest in a range of Victorian and later potters such as Royal Lancastrian, William De Morgan, Moorcroft and the Martin Brothers.
The sale will be the first held under the new name of Kinghams. After buying out partner Gary Orme, George Kingham is now the sole owner of the business.
