The stamps of the Canal Zone
A 1916 Boston catalogue of Canal Zone postage stamps, compiled by William Evans for collectors of philatelic issues from Panama. Its pictures are black-and-white reproductions of stamp designs, many showing portrait medallions, ornate frames, and printed denomination numerals such as 1, 2, 5, 8 and 10 centesimos de balboa. A designer might take from them the layered border systems, oval portrait frames, and bold numeral placement typical of early twentieth-century stamp engraving.
