This stamp is the third in Canada's new regular issue series. The design was executed by Mr. Ernst Roch of Montreal, an internationally known artist and designer. The portrait of Her Majesty is executed in a simple almost classic style giving a cameo appearance to the stamp. In the upper left corner of the stamp is a symbol to represent one of the primary sectors of the Canadian economy. The symbol on the four-cent stamp is an electric high tension tower representing Canadian industry. Canada has moved from a principally agricultural country at the time of Confederation in 1867 to its present position as one of the world's most important manufacturing countries. Manufacturing now accounts for more than 26% of the value of all goods and services produced in Canada annually. The growth of the construction industry in Canada has kept pace with manufacturing expansion. In 1960, 23% of the gross national product was devoted to expanding, modernizing, and renewing the nation's production facilities. An increase in urbanization which accompanied the industrial expansion had led to one of the largest home building surges in history.
