1930s Series (2 1/2" X 3 1/2")

Dating of this series is based on the fact that the labels were obviously published after the Royal York was opened in 1929 but before the old Hotel Vancouver closed in 1939.   Based on this dating, it is extremely likely that the complete set must also have included the Algonquin Hotel.  And, depending on the exact year these labels were printed, there may also be versions for Digby Pines (purchased by CPR in 1931) and Place Viger (operating until 1935).  

1940s/1950s Series (5" X 3")

The corporate font used in this sticker appeared in advertisements from 1934 to 1958 and in the official corporate logo from 1946 to 1959.  The style of illustration is also very similar to ads from the late '40s and early '50s.
