This homemade toy truck was brought into Canada by the young son of a foreign intelligence operative sent to Canada for the purpose of carrying out espionage tasks. The operative and family entered Canada from Eastern Europe in the early 1960s. As can be seen, the "toy truck" was a cleverly crafted concealment device for espionage paraphernalia. It contained a microdot reader, a special lens and a miniature code book called a One-Time-Pad containing a series of five digit numbers. Codes would be utilized once and then discarded, hence the name.
