I’m not familiar with the Page & Shaw candy company. The only information I can find seems to point to Page & Shaw Inc. being one of the nation’s top candy makers in the early 1900s. Judging by the product pictured, it appears they were similar to a Whitman’s/Russell Stover. It doesn’t appear they are in business any longer but I did find an interesting article from the New York Times (PDF format) from July 20, 1918 about the Federal Food Board shutting them down for a week because they had stockpiled more sugar than the Food Administration permitted.
The ad above is from 1956 and I have to say, this is a pretty creepy painting of Bob Hope. He looks evil. Apparently he was somewhat of a spokesman for Page & Shaw though because I found another ad he did (same pose, but this is a photograph) in 1955.
