The City of London recently upgraded their largest baseball scoreboard, surrounding it with top, bottom and side advertising panels. This scoreboard features third generation Surface Mount Technology (SMT) LED digits that offers superior viewing angles and proven reliability over time. OES Scoreboards’ technicians completed the upgrade in just two days, to Model 7223 that was installed a year ago. What a great scoreboard for the London Majors and the City and the world’s oldest baseball grounds.
