Spotted on the skyline above Albert Street as it heads to and from Mayoral Drive today: an old Summit shirts sign painted on the back of one of the buildings.
The Summit brand still exists, part of the firm Ambler & Co which was founded by Fred Ambler in 1919. The company's slogan, still used, can be seen: "No one ever regretted buying quality." The Summit brand seems to date from around 1927.
