LONDON – Chiswick Auctions will sell the collection of a former British journalist and presumed diplomat who gained access to some of the world’s most secretive countries during the Cold War era. From the 1950s to the 1980s, John Newell spent time in places such as North Korea, China, East Germany, Russia, Tibet, Zanzibar, Alaska, and Panama for both work and leisure at a time when many of these areas were largely off-limits to westerners. The collection will be sold during two auctions without reserves or estimates, with the first part being offered on Wednesday, March 1, and part two scheduled for late July.
