After selling other collections, at CAPEX ’96 Warren Wilkinson extended a previous interest in the philately of Canada and British North America with the purchase of the Charles Firby collection of Canadian Pence covers. Developing the Pence collection caused him to expand into other BNA areas, including New Brunswick, Nova Scotia and Prince Edward Island, as well as British Columbia & Vancouver Island. He proceeded to win an unprecedented three consecutive Grand awards at the annual British North America Philatelic Society BNAPEX exhibition. His ‘Postal Rates of Canada 1851-1859’ won at Ottawa in 2001, while ‘Postal Rates of New Brunswick and Nova Scotia’ received the honours at Spokane in 2002. In 2003 Warren won again at London, Ontario with ‘British Columbia and Vancouver Island Postal History: 1850-1871’. In the same years these exhibits also won the Grand award at the Royal Philatelic Society of Canada exhibition.In 2004 the Prince Edward Island Postal Rates – January 1, 1860 – July 1, 1873 exhibit, built in part on the Dr. Robert V.C. Carr collection, received Gold at BNAPEX in Baltimore, Gold and the APS Grand Award at BALPEX in Baltimore, and Gold and the Grand Award at the RPSC exhibition in Halifax. Since 2004 Warren has added Pence and other covers from the Cusworth collection as well as other acquisitions, expanding the exhibit’s date range backward so that is now from July 1, 1851 to June 30, 1873. It is this much fuller and spectacular collection that is being shown in this volume of the BNAPS Exhibit Book series. In 2005 the exhibit received Gold and the Myerson Award at BNAPEX 2005 in Edmonton, and Gold at the APS Champion of Champions show in Michigan. In 2007 it was awarded Gold and the PHSC and BNAPS awards at the Plymouth, MI show.
