This was Millwall's last first-team home game as a North London team, although they were as close to being a South London team as they could be. This was played at their North Greenwich ground which was on the southern tip of the Isle of Dogs. Their reserves played Clapton Orient on 15 October at North Greenwich, and the first game at The Den was against Brighton on 22 October.
The move to The Den was supposed to have happened before the start of the season. The delay resulted in the programmes up to this point containing adverts mostly for businesses based in the New Cross area despite Millwall still playing on the Isle of Dogs.
Although Millwall were located in North London and Woolwich Arsenal in South London, Arsenal's ground was further north than Millwall's!
The London FA Challenge Cup had been inaugurated in 1908 when the London Football Association finally bowed to pressure from the Football Association to allow professional teams as members. Arsenal had left the London FA in 1891 when they turned professional, followed by Millwall in 1893. This competition was competed for by 16 teams made up of London's professional teams with the remainder being the city's best amateur teams. Towards the end of the 1920s, the professional teams started to field reserve teams rather than their senior team.
The co-editor of the Millwall programme was George Heritage who worked in the Royal Arsenal as a clerk, and also edited the Woolwich Arsenal programme. To give an idea of how football has changed over the last 100 years, George had Harry Logan, who Arsenal had signed from Sunderland during that summer, lodging with him!
