Explorers of Canada on First Day Covers, by Gary Dickinson, 2015. Spiral bound, 118 pages, 8.5 × 11, colour. ISBN: 978-1-927119-53-2. Published by BNAPS; Stock # B4h923-075-1. C$57.00. In the first of two books being published by BNAPS this summer, Gary Dickinson continues to show how much variety there is to be found in Canadian First Day Covers. Although Jacques Cartier and Samuel de Champlain were depicted on stamps as early as 1855 and 1908 respectively, it was not until the Cartier stamp of 1933 was issued that any of the men whose efforts served to open up the continent for further exploration and settlement was honoured by being the subject of a Canadian First Day Cover. The quality and variety of designs of Explorer related stamps and cover cachets is quite surprising.
