This is a primer on the Danish Ore bicolors of 1875 - 1905. The book is filled with clear, oversized illustrations in color and includes a number of tables consolidating information on this particularly complex subject. The narrative is succinct and to the point on everything from frame designs, to color, to postal history. It is geared to the beginning Danish collector or specialist, and is useful to the intermediate specialist because of these traits and its design as a workbook that can be easily opened while studying individual copies. It is priced at $40 post paid in the U.S. (S/H overseas must be discussed with the RMPL). Available from the RMPL.
