I have recently found an old bus ticket in a 1905 edition of a book – images of the ticket are above. It measures approximately 2.5 inches long and 1.25 inches wide.
From a brief look at the internet, it would seem that this ticket was issued sometime between 1908 when the London General Omnibus Co bought two other companies, and 1912 when LGOC was bought itself. Would you agree?
