Gregory's Sydney Street Directory -- The Sydney car driv?er's most indispens?able accessory turns 50 next week. Gregory's Street Directory is going gold, and to celebrate their 50th edition the company is producing a special limited leatherbound edition along with the normal hardback and softcovers. And how the city has changed since Cecil Albert Gregory wandered the back streets of Sydney in the 1930s i making maps in his spare time. A skilled cartographer who also dabbled in hypnotism, Gregory drove over every one of some 15,000 streets in the city preparing for the first edition, which sold around 5,000 copies in 1934. December 05, 1930.
