Found a few "ghost signs" in my visit to Chicago.
The Boston Store was a department store that opened in Chicago in 1906. The store was bought by Federated Department Stores in 1948 and was close soon after.
Amazon Hose & Rubber opened in Chicago in 1919 and is still in existence today at three Florida locations. They no longer exist in Chicago, however. Looks like windows were added to this building some time after this sign was painted.
