These cards are from a series of 120 cards issued in Canada by the World Wide Gum Co, Ltd. of Granby Quebec Canada in packs of their Marine Bubble Gum. No Guide that I am aware of has this series listed, and I have never found reference to an actual date of issue. I assume that they were issued in the late 1930s or 1940s as the subjects seem to mostly World War 2 Naval Ships or earlier. The card front feature a blue toned photographic image of a ship from the Royal Navy (both Canadian and British ships) with the information about the ship written in both French and English printed on the front. The front also indicates that their were to be 150 cards in the series. However no numbers higher that 120 have ever been reported (if you do have a card number higher than 120 please email me and let me know I would be interested in seeing it, for my references). These cards were issued with blank backs. These cards measure 3 1/4 inches by 2 5/8 inches.

This Gum along with Aviation Gum and Victory Gum were apparently referred to as the "Big 3" and Big 3 Premiums were issued.

A wrapper for this gum is shown on the right. The wrapper image is courtesy of Bobby Burrell who is the author of a book titled "VINTAGE HOCKEY COLLECTORS PRICE GUIDE". This wrapper indicates that there were 150 cards in the set.
